Detailed Answer:
Hi
Welcome to HCM.
I have gone through your query.

I feel, It is not exactly allergy to heat. I would think of a condition known as cholinergic urticaria.
It is a simple benign condition when increase in body temperature, either due to exercise, heat exposure, fever, etc causes red/pink itchy lesions over skin in any part of body, which usually subside by themselves.
To control itching, I usually suggest my such patients use of antihistamines such as levocetirizine or cetirizine.
Please do not scratch the itchy areas as it would aggravate itching.
One more thing that I would like to advice is to go for thyroid function test, as similar symptoms do occur with thyroid disorders.

Hope this helps.
Take care
