I had no allergic reaction at the time of vaccination. Felt fine. My arm hurt and I just felt slightly tired that day but nothing compare to Dose 1 or 2 or even 3 where I felt slightly run down.  My arm was really the biggest pain, no rash around the injection. Overall I took these vaccines well compare to my partner who ends up with elevated heart beat and increased body temperature and in bed for 1-2 days every single time.   I initially thought when I got the rash on the 09/30 that maybe the rash was caused by something I ate or drank, me having 2 coffees because my partner brought me another coffee for the afternoon since we had an event we were putting on at work. I was very stressed too so we even thought that maybe me stressing out gave me hives, it would've been first but even that was considered.   My morning coffee at home that day was with the OM Mushroom master blend I've been taking daily for the past 2 years, I usually mix this mushroom mix + ginkgo biloba, green tea powder, turmeric and cinnamon into a coffee mix for a superfood type power drink but the spoon I use is 1/4th of the tsp, very tiny.  I never had any issues but figured maybe with 2 coffees and this mix plus stress, my body was acting up.   So I stopped all of this expecting that next day I'll be fine. Essentially I did not drink any caffeine, soy milk, cow milk, coffee and stopped my multivitamins and all of these additional things for 7 days (pretty much all of the typical what you consider allergens) to get to a neutral base and the rashes keep coming back every day.   I honestly have never seen this. Have photos I can send. The hives get bumpy like mosquito bikes, itch like crazy, skin rises and gets red then 15-20 min later it all disappears and starts up somewhere else.    The rashes intensify at night, I've read that histamine spikes at night so around 8pm it's a sure thing I start to itch but today for instance it started the moment I woke up just not as intense and came and stopped in waves throughout the entire day.    Having traveling hives from the vaccine was the last thing I thought to search online for because I had Moderna vaccines on 01/13/21, 02/10/21, 12/02/21 and had zero adverse reactions. But when I stopped taking all of this, stopped drinking coffee, soy milk, cow milk and the hives kept coming back, especially at night, then I figured what else changed....and came to the conclusion that the only thing I did was get the shot. We also tested several times and had no covid, still wear masks everywhere and I never had covid.   Overall today the hives are not as bad as they were initially but still happen every day since 09/30 and travel, right now I have it on my left hand and left leg, 30 min ago it was on my back and neck and under the front of my bra. The rims of my eyes sometimes itch but not as much and face once in a while or back of the head. Even my inner thighs itches so there hasn't been a body part...even soles of my feet including toes...an entire body histamine overreaction, it's as if my body is stimulating histamine release that's just out of control.    You can call me to ask questions. I hope this helps. I took antihistamine and it helps but makes me drowsy so have to try zyrtec next.
