Been suspecting an allergy towards it for a long time but doctors didn't believe me and said local treatments for thrush shouldn't cause a reaction all over the body. Well last night I had a severe one, chest tightness, tight throat, rash on face, chest hands and feet. Feeling sick and abdominal pain. I obviously stopped the treatment and doctor has given me piriton to take but my symptoms keep coming back. The pessary I have taken 2 doses and it has not fully dissolved, still stuck inside me. Could this still be causing the reaction. My chest tightness keeps coming back and I'm worried. Ambulance have already been out once and my obs were fine said it looks like antihistamine is working but I feel like it only works for a short while and comes back. Any advice?
