itchy rash when body heats

[clarence333]

im getting this kind of itchy rash ( in my arms, chest and back ) when inside of my body heats up, its so wierd coz after 10-15 mins all of them will disappear..anyone knows what causes this? maybe cold weather? coz this happens to me lately when the cold weather starts in cali, it doesnt show's up everyday, just only when my body heats up, or sometimes if i have a feeling of goosebumps my body reacts to heat and starts showing these rashes.. please help

Hello,
From the symptoms it can be urticaria or hives. You can take some OTC oral antihistamine medications like Benadryl or Claritin and see if it helps.

Also use mild steroid cream after consulting your doctor.
If still the symptoms do not improve then please get a clinical examination done by a dermatologist.
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 dermatologist. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.

This is normal. It is just your body's reaction to extreme fluctuations in temperature. It can be especially itchy if your skin is dry or sensitive.
Try to stay hydrated and keep your skin well moisturized.
