I also have a dry cough, fast heartrate, and sore throat. Is it supposed to last till the next day?

My MCAS flairs also feel like this, and i get confused about which causes, which at times.

I wonder if it's more PEM or POTs since I overexerted myself alot prior.. and the high histamine flared me? I also have a migraine..also do your flairs start with a dry cough that worsens and makes it feel like you're having an allergic reaction? And even antihistamines won't touch it.

Lately, I've been working a lot around the house and wore a mask while doing so. It involved strenuous activity, and suddenly after sitting down I started feeling sick and couldn't breath as if i was suffocating and experienced brain fog, dry cough and confusion and it lasted hours, felt as if I had inhaled a lot of dust?

even though I didn't. For some reason, I feel it more downstairs. I vacuumed the room and got rid of potentially dusty items, but I still feel this way.

I have a dry cough, a worsening sore throat, and extremely low blood pressure. Even blowing my nose releases hot air, as if I have a fever, but it's not a fever.

I'm wondering if it's dust I'm suddenly reacting to or if it's from overworking, maybe caused a histamine dump? Or have I overworked and am going through a flare?

I have MCAS as well so my POTs and CFS/ME also correlate and i cant tell which is which at times.

I'm extremely sensitive to fragrances, mold and dust, etc, and someone in my house used a fragrance product hours. After that, I randomly developed fast heartrate panic feelings, and sore throat feels like I inhaled heavy amounts of dust. Wheezing and even nasel congestion (I have nasel polyps, so my nose tends to be mildy congested all the time) Maybe the moldy fridge finally got to me?

I also took an antihistamine, but it seems it didn't get rid of the sore throat even till the next day. Im very worried that I have developed a new sensitivity to something in my environment and suspect my mother placed a potentially moldy item in the same room, and it may have caused my MCAS to go haywire? I wonder if starting ketotifen gets rid of this?

I tried getting rid of many items from my room, yet i am still reacting? Is it my phone Playstation? Mind you I always keep these things dust free and do internal cleaning. Maybe vacuuming the room will help? But then I'm experiencing this in all rooms? Haven't went into anaphylaxis yet. There was mild tightness in my throat, but I don't feel it anymore after antihistamine? Or is it just my brainfog causing confusion.

I'm hoping it's just a sore throat caused by dust, maybe? I can swallow food, but I have a constant dry cough with a sore throat, brain fog, and confusion. Also, feel warm and have low bp. Does popping ketotifen get rid of this for you?

I don't even drink alcohol, and right after eating, I experience shortness of breath, vertigo, and brain fog. Google ai told me it's anaphylaxis, but it's not.

I also have MCAS and i can't always tell which condition is causing which symptoms at times. If I do anything involving strenuous activity and then sit down, I experience brain fog, shortness of breath, and tremors. I also wake up with vertigo and even after blowing my nose, i experience vertigo, which makes me think the vertigo part is more connected to my Eustachian Tube Dysfunction

When I'm in a flare, I have chronic shortness of breath that makes it seem like I'm having an MCAS reaction, but my MCAS reactions always involve throat tightening, a panic attack sensation, and a sore throat when near an allergen.

I've reached a point where I can barely function anymore. After cleaning, i feel like I'm having an asthma attack (even though I wear a mask), and now even eating causes shortness of breath but not throat tightness, as if I'd smoked a dozen packs of cigarettes Asthma runs in my family, but my symptoms only began in my 20s, i believe after mold exposure and a virus. I wonder if it's the antihistamines i'm taking causing all these bizarre symptoms or maybe causing a flair. (I am diagnosed with POTs and ME/CFS)

Do you experience MCAS and have sensitivies to objects around the house? Not just food, as in even if that object isn't off gassing or has a smell. Any electronic devices or even decorative items? Toys? Mine are permanent, so i can't be near those things anymore, and dust definitely flares me unless I vacuum it.

I have chronic post nasel drip that antihistamines don't touch and i only get respiratory reactions, sore throat, low bp shortness of breath and confusion when near an "Allergen" and rabid heartrate, feeling of anxiety.

Which makes my family think I'm lying about my sensitivities..

I am chemical sensitive and have sensitivity to certain soap and shampoo scents. So this can make showering hard, especially because there are rarely any non scented products sold here.

So far, i'm only taking an antihistamine (Loratadine) and montelukast. I'm too afraid of starting ketotifen since I have dry eye and antihistamines already make my dry eye feel worse. But I know that with every chemical exposure, it will get worse, and so i'm begging my visiting sister to not use perfume or any scented thing. This disease has ruined my mental health. My sensitivities have only become worse in 2026, and I'm paranoid of becoming sensitive to electronic devices.

I guess I'm a rare case where my allergies/sensitivies will stay permanent. Is it even MCAS?

Or something else going wrong with my mast cells where it will perceive everything as a threat, kind of like central sensitisation.. POTS, Dysautonomia, CFS/ME? From what I have observed, i do infact have multiple chemical sensitivity, which is part of MCAS, all of which kickstarted from prolonged mold and perfume exposure. P.s. doctors in my country do not diagnose all of these conditions, so they will gaslight you into thinking its all in your head and just allergies, worse treatment if you're a woman..I legit have been ignored by doctors in the past where they'd check my dad first and just dismiss me with antidepressants. I suspect my dad also has some sort of MCS stuff going on but not as severe. (He stopped wearing cologne but has no issues with soaps, shampoo, and shaving cream fragnance) I do infact experience POTS and ME/CFS like symptoms if I walk around too much and then sit down, rabid heartrate, tremors, confusion, shortness of breath and overall weakness. Happens after working around the house, too.

How many of you have sensitivies to objects around the house? Not just food, as in even if that object isn't off gassing or has a smell. Any electronic devices or even decorative items? Toys? Mine are permanent, so i can't be near those things anymore, and dust definitely flares me unless I vacuum it.

I come from a country where poor people will pop out kids 24/7 and eventually end up with 12+ kids, and then force labour on them. Knowing full well that they can't provide for them well. I believe poor people, especially, should not have kids, mostly because of the financial burdens and how the kids will eventually grow up miserable and in poverty, growing up begging, etc.

It creates a cycle of misery. Child labour is still a huge problem here, and rich families even buy child maids who are horrifically abused in all ways. I’m not a fan of kids, and I never understand how people can just think they must have more kids, and that one is not enough.

They screech for no reason, and it annoys me, and I already have hyperacusis, so I will never understand why my mother decided to have five kids (two of us were, unfortunately, twins). I'm one of the twins, the rut of the litter, developed disabling autoimmune conditions later in and i am miserable to this day with MCAS, POTs, DED, chronic anemia and guess which parent i inherited my asthma allergies from? My father, not only do I look more like him, i have his bad lungs and the mold gene. (He used to smoke until he developed asthma)

I get that my mother didn’t have a choice because of an abusive marriage that she was trapped in, and her father didn't want her back even when she begged him to. Both my parents didn’t get along but never chose the other option? My cheating father got his gf multiple abortions but didn't think to do that in a failing marriage. And we grew up horribly neglected, with severe mental health issues and autoimmune conditions, and now we hate each other. People who don’t get along and have kids and then just neglect and abuse them are incredibly selfish. Both my parents were immature and probably didn't want kids. We were just pets on our own.

I’m 26 and from South Asia (Pakistan). For years, I lived in moldy homes and after a fever, I developed mysterious allergies: My legs started aching, and i became bedridden and extremely weak; I couldn’t even keep my eyes open or eat by myself. I had to be kept on a glucose IV (this was not in the COVID era). I don't even know what kind of virus I had. I was, however, chronically sick throughout my childhood, used to get frequent fevers, and even had jaundice at one point when I was very young.

Months after I ordered some toys from a secondhand website: I developed a fast heartbeat when I was near them. The symptoms progressed to a sore throat and a tight throat, shortness of breath, along with low blood pressure and severe weakness. I realized it was an anaphylaxis-type reaction and that removing the toys from my environment was the only thing that relieved my symptoms. I was heartbroken and confused. I was only 19, and I started experiencing mental breakdowns over this, I was already a stressed and sensitive teen, but nobody ever bothered to get me diagnosed instead I was gaslit. My family didn’t believe me and said it was all in my head. I never get physical symptoms but more respiratory symptoms like swelling and hives. I can touch toys but with a mask on. Later, I had the same kind of reaction to felt, soft bendy wire, foam, all perfumes, cologne, spray paint, nail polish fumes, glue, all typed of pencils, crayons, all paints, all toys and markers. Which is sad because I loved to make drawings and crafting.

As of 2026: I eventually found out that I am extremely sensitive to mold exposure and have confirmed MCAS and that it had been worsening whenever I had mold, dust and perfume exposure. After moving into a new home that wasn't as moldy and the walls had been repainted after they scraped off the moisture damage, I always beg my family members not to wear perfume or cologne when visiting or around me. My all-in-one desktop also had mold inside. Right after this, i developed a sensitivity to my phone case. Around the same time a toy had mold, and I came in contact with it (I had specifically told my mum to throw those toys away, and she decided to take them out instead) She doesn't listen, she never freaking listens and now I'm allergic to most phone cases.. and my old phone... this is insane and unfair.

Since then, I’ve had chronic wheezing as if i have a respiratory infection going on, symptoms similar to POTS after eating or working (though not true anaphylaxis), and I get tremors and brain fog if I walk too much. All I'm told is to use an inhaler... and antihistamines

I also discovered that I have eye allergies, causing dry eye, and my eyelids would swell. I suspected it was an allergy (which it did turn out to be), so I started taking antihistamines and then noticed an improvement with my sore throat from multiple chemical sensitivity as well. My eye issues could be related to MCAS because I'm sensitive to certain sites and apps, which is odd I take loratadine and montelukast since I also experience shortness of breath alot. I had to cut out sugar and suspect chocolate triggers inflammation that leads to MCAS reactions, too.

Asthma and allergies run in my family, but im not sure if anyone has MCAS. I’ve noticed that my father stopped wearing cologne a few years ago. I wonder if a certain gene came from him, he used to smoke until he developed asthma, and i seem to have almost all similar health conditions.. I also have beta-thalassemia, which is genetic and has always shown up in my blood tests.

It’s extremely difficult to find anyone in my country who suffers from MCAS, MCS, or POTS, or who can offer any support. I’m constantly paranoid about mold and about developing new allergies, so I wear a kn95 mask and keep spraying vinegar in the bathroom and everywhere to prevent mold.

My family still doesn’t believe me, and I am disabled in multiple ways. I have PCOS, hyperacusis, tinnitus, MCS, some sort of histamine intolerance, screen sensitivity, and chronic migraines. I can’t stay active anymore because of the POTS-like symptoms. I’m in agony every day. The most difficult part is that there’s no doctor here who even diagnoses these conditions or would prescribe me meds to control my MCAS. They think it's just allergies.

I connect my symptoms to MCAS, because they don’t feel like normal allergies. They keep worsening, and my immune system is also extremely hypersensitive to stress and to the smallest allergens in the air. On top of everything, I also have a dysfunctional family environment. I'm contemplating if I should start ketotifen.

I got a random notification on my Google account to confirm my age right after verifying my YT live and then went live for hours.

I'm 26 years old but don't sound my age, and maybe the YouTube AI thought i was a minor when speaking on live. Another conclusion is that someone may have reported my live that i may be a "minor"

They said i will lose my google account in 14 days. Mind you, I never got this age verification email for years on this account only until I verified my YT live via my phone number.

The email, however, wasn't linked to YouTube, but Google. This account is linked to my YouTube, and 100% believe it's because of the live thing. I have so far confirmed that I am not a minor with the method they were asking.
