I was given a new strong probiotics to help me re building my gut flora after years of antibiotics, gut issue and heavy white tongue coating ! i was doing good on them but after 2 weeks i had an allergic reaction to banana while i never had any allergies before that except when in the first 6 months of me getting the infection which lead me to CFS ! when i ate the banana my lips got swallow and i took an antihistamine pill and it took 2 hours to get better , 3-4 days ago i was drinking tea which i never have a problem with it and suddenly i had a moderate lips swollen , shortness of breathing and high blood pressure , took antihistamine pill and went to the ER after it , my oxygen level wasn't that bad (94-95%) then it went better after 1 hour from taking the pill so the doctor gave me 10 pills and asked me to take one daily now its my forth day and my lips are still lil mild swollen and if am late on my pill they will get bigger and my chest will get worse !! did those pribitoics made my immune system works wrong ? overactive which caused my allergic reaction or what ever is going on ?! it seems they are swollen even if i doesn't eat or got into anything how to fix this ! any ideas ?
