Monthly anaphylactic shock episodes - unknown trigger
As the title says, I've been having these episodes monthly since February of this year. I'm not sure what's causing it which is the scariest part. If anyone out there knows what it could possibly be, I'd really appreciate the insight. Quick summary about me+the situation:
- 31 y/o female in Delaware (lived her for past 4 years)
- have never had any kind of allergies
- pregnant last year, delivered 4/2025
- our dog has been with us for 3 years, my parents cats moved in December of last year after my dad passed (my mom moved in with us). I've never been allergic to any of them
- first episode was 2/28 - went to ER where they confirmed it was stage 3 of 4 for anaphylaxis given every system was responding and I was given an epi + a Benadryl injection on the opposite arm. My throat almost closed up.
- next few episodes (3/15, 5/14) I was able to do without an EpiPen but it was still pretty severe (entire body in hives with UNCONTROLLABLE itching, completely clogged nose (unable to breathe but still runny)... lightheadedness, racing heart, difficulty breathing and wheezing) - managed to just let it ride out
- Last nights episode (6/6/26) it was again at home and again at night - this always happens at night. I felt the first few symptoms (uncontrollable sneezing, runny nose, itchy throat and itchy eyes) and ran downstairs to take a Zyrtec. It kept progressing. I started to wheeze, couldn't stop coughing and sneezing and my eyes were itchy and blurry. I started having difficulty breathing so decided to use the EpiPen. I couldn't stop itching my entire body and it was all swollen afterwards. It took about 90 minutes to completely go away.
- ZERO common denominators across all episodes when it comes to food, activities, clothes, location etc
I have other issues that I'm not sure are related but wanted to see if anyone could help point me in the right direction with the above. Overall, it's Gl issues like bloating after meals and excessive gas/burping and what I think might be beginning stages of arthritis. (Dull pain in fingers most of the time, worse in the morning, one finger swelled up for 3 days a few weeks ago and I couldn't even bend it.
Appreciate any insight at all! 🙏🏽
