I know this is going to sound weird, but i have been breaking out from sun exposure fro the last 10 years or so. Recently I got a scald burn on my wrist and I developed a rash from the burn. I am wondering now if I have some type of reaction to heat or what. It's just really weird. It breaks out in bumps that itch like crazy and takes about a week to go away. Has anyone ever heard of this and what can I do for it?
These symptoms can be due to solar urticaria. Apply a good sunscreen with minimum spf 30 atleast half an hour before going out in the sun. You can take non-sedating antihistamines such as Cetirizine or Loratadine(Claritin) when the rash appears. Short courses of oral cortisone or steroids are taken for short periods (one to three days) to settle more severe symptoms. You may take Vitamin C along with the prescribed treatment. Vitamin C is a general anti-allergy supplement. Also apply calamine lotion and a mild steroid cream like dermacort on the rash.
To prevent solar urticaria in future, desensitization using phototherapy and photochemotherapy are often advised.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care.
