Skin Care and Diseases

Itchy rashes with slight fever



I am a senior, age 53. Frequently, I get small, itchy, prickly heat type, rashes on my chest or arms, that last less than an hour. During that time, my temperature rises slightly (99-99.2 degrees). Afterwards my temperature returns to normal. I also have multiple joint stiffness, and nausia. (I have been tested for Rheumatoid arthritis-RF-and it was negative.) Please comment on other rheumatic causes of the rash.


Your signs and symptoms suggest that you do not perspire well when you raise your body temperature.  This form of acquired or even congenital hypohidrosis may lead to temperature rises and your skin remains dry.  It is important for you to see your board certified dermatologist.  There can be several tests that will define your process and get help.
