Hi,
People who have a physical urticaria have a physical trigger for their hives, such as pressure, heat, cold, sunlight, water or exercise. Up to 20 to 30 percent of people with chronic urticaria have a physical cause.
Cholinergic or heat urticaria is a form of chronic hives that is caused by an increase in body temperature. Hives are caused by any increase in body temperature, such as hot showers, exercise, spicy foods, or being under too many covers in bed at night. Strong emotions may also cause hives to occur in people with cholinergic urticaria.
A person’s symptoms, along with triggers that increase body temperature, are suggestive of cholinergic urticaria.
The best treatment for cholinergic urticaria is antihistamines. While any antihistamine is likely to be helpful, older antihistamines, such as hydroxyzine, seem to work especially well.
Severe cases of cholinergic urticaria have been successfully treated with danazol, which is an anabolic steroid. Use of this medication is limited by its severe side effects, however.

My son is like you somewhat. He is okay in the winter though. It is just now that he is starting to have problems. Today is the first day of the year that it is really hot and very humid where we live. I made him take the trash out and he was out about 5 minutes and he came back in and was complaining of the itching. It was driving him crazy. His skin was red in very large patches almost covering his body. I am really worried about it because clearly it an allergy to something and if there is such a drastic reaction could it affect is breathing? I had him take a benadryl and a shower. It did help a lot. His isn't as wide symptomatic as yours.
Have the Dr.s done an allergy test on you? I would try going to a dermatologist if you haven't already done so. But hang in there surely there is a Dr out there that will give you the care that you need although now days it seems harder and harder to find one.
