After the park run on Saturday I started to feel burnt on my neck...it got worse overnight and since Sunday morning I have a burning itchy rash all over my neck and face which is absolute torment and my face is a bit swollen. The only relief is cold compresses and I'm dosed up on antihistamines. I also feel a bit generally unwell and was aware if becoming a bit shivery during the park run. I drank water, wore a hat etc. It's happened before and gp has diagnosed photosensitivity due to side effect from medicine. Weird thing is that I am often perfectly ok in the sun. I want my body to be normal so I can get back outside!
