my sister thinks she is allergic to the heat because when she is in the sun to much or takes a shower with hot water she gets like rash or really noticable red spots all over her legs when she is wearing shorts and none of her friends have that so is that normal
What you describe is abnormal. A rash (usually urticaria or “hives”) following exposure to the sun might be described as a type of allergy. Exposure to hot water can cause redness of the skin, especially the hotter it gets. If the lesions with a hot shower are individual spots that would be what is called heat urticaria. The most effective treatment for each of these is the avoidance of hot water and sun exposure.
No treatment is required if the spots do not result in annoying itching.
Your sister might want to visit the Mayo Clinic web-site or consult with a dermatologist for further information.
