I tried cleaning it and this happened
Will the gray come off?
Just to be sat I’m totally fine cutting out acidic foods but I’m at a point where the ic diet is not even safe for me and I worry if I left my chicken in the fridge to long and it created histamine please tell em it gets better ?!!
Well it’s been a year and a half of this hell I’m just 21 years old male and my symptoms are mainly discomfort as bladder fills and symptom relief when peeing I void like every hour, sometimes every two, diet helps somewhat it could be the difference between peeing 8 times a night vs 1-3 a night, but still flare with basic foods like plain chicken and rice I’ve done the elimination diet, and if I fast symptoms will calm for awhile anyway I did PT with Nicole cozean office who supposed to be a ic expert didn’t help at all really, food trigger is probably my biggest so I don’t have pelvic floor dysfunction, Botox didn’t help much I don’t have spasm, I don’t tolerate amitritplyne well, antihistamine help in a flare, but I’m feeling this is my best option, I also am slightly optimistic because my bladder at times has shown I can sleep through the night and just wake once filling almost a enter 8oz water bottle or the small ones and also sometimes I can tolerate during the day but very rarely any advice or success stories with insertion I should know about than you for the continued support.
When I drink enough water and my pee is a lighter yellow I know not clear as that is over hydration but like a light yellow many people say that it helps symptoms but for me it makes no difference I still have to pee regardless, is this indication that urgency is mostly my issue or pain? I mostly feel better after I urinate but urgency is what I feel as bladder fills but it hurts to hold it in as well so I’m not to sure
If feeling no pain after urination but pain as it fills is that urgency or pain
