I get this swollen rash on hot holidays but it has started in the uk in the heatwave.
It's sooo painful my feet are on fire.
I thought prickly heat but it came on over night and my feet aren't noticeably sweaty (obviously I am sure all feet do sweat) and it looks nothing like the images on Google.
It is painful to touch like fire! The white background is home and the darker background is on holiday how it ended up. I can't go to GP.
In pharmacy in greece gave me antihistamines and hydrocortisone did nothing I seem to recall.
