Hi, wondering if i could get some advice?? Every year, usually in the summer i get a sore on one side of my face(always the same side)which develops into blisters and is very painful, the sore sits right around my cheekbone and is acompanied by swelling which reaches from my eye (which then sags) right down to my neck, this usually lasts for just under a week and then the sore starts to heal. I am then left with a scar which stays with me for around 6 months. The last time i had this was this summer whilst camping in France, the campsite had lots of trees and scrubs, was wondering if that had anything to do with it?? Just can't but my finger what the cause could be... I suffer for migraines and get headaches when i eat strong foods like garlic and chillis, always have a blocked/itchy nose, most days esp if it rains i have a headache, really bad if i'm exposed to damp/mould. Usually by the time i get an appointment with my GP my face is in the healing period so my GP just tells me to come back if it happens again as he has not got a clue what it could be... Any advice would be appreciated.
