Seems many here have those that affect them and those that don't. I think my first flare came after a double dose of amoxicillin. BUT - recently I had sinus infection - twice - and took a z-pak which is closely related to amoxicillin (penicillin) and did fine. It would be interesting to find out about
the shot - seems like a good idea! I always double up on probiotic Align when taking the antibiotics.
