This is a weird one (and very long - sorry) and if anyone can point me in the direction of a solution I’ll be forever grateful.
Some years ago, I had a strange, unexplained flare-up of horrendous hives all over my face while staying with family, and saw my GP, to no avail - they couldn’t understand what had caused it, decided it was an allergy of some sort, and prescribed fexofenadine to take in case it happened again. The tablets seemed to work and the problem completely went away and never returned when I was back in my own home. I’m not an allergy-prone person at all normally.
I assumed it was a strange one-off…..until a few weeks ago when, back here again, my face and neck suddenly blew up dramatically within a couple of hours. My face goes horrifically red (I'm pale-skinned normally), unbearably itchy, it puffs up. My skin is burning hot and I feel like I could rip my face off trying not to scratch. It’s just my face and neck, ie the uncovered bits of my body, that seem to be affected.
I’m having to visit and stay here a lot at the moment. And the last two times I’ve had this same reaction. It’s completely baffling but also very worrying because it’s now seeming to happen quite quickly after I come into the house. Never happens anywhere but here.
The house is old and has had woodworm treatment but googling suggests insect bites don’t produce this kind of reaction. I’ve wondered if it could be dust mites - but I don’t have any kind of wheeziness or hay-fever type symptoms, only the skin thing. It’s the awful, extreme nature of it that worries me. And despite the fact that I've known the house forever and spent large chunks of my life here not having this problem at all.
Apologies for the essay but can anyone think of any reason why this is happening? And what I could do? The GP seemed baffled so I guess a dermatologist? The usual things are all the same as I normally have, washing powder etc.
Sorry for the huge essay ☹️
