Hi, A few days ago I woke up in the morning with tiny red bumps in blotchy areas on both my legs and calves. They were small red, circular and itchy. Nothing to overwhelming but just in a few locations. After about an hour they dissipated but throughout the rest of the day I had a few appear in random location and move the the upper part of my body until finally feeling the itchy sensation in my hands. That was Saturday, it is now Thursday and although I dont really get the bumps anymore anytime I scratch myself on my body within about 20 minutes it become red, turns into a welt, and become very itchy for a short period of time. Please let me know what you think this might be.
Such a rash which appears and disappears is due to hives skin. Avoid using any lotions and creams for the meantime. Use a mild cleanser with moisturizing properties like Cetaphil. Also use cotton clothes and change the clothes twice if there is any increased sweating. Try keeping the skin free of sweat as far as possible. If the symptoms still persist then you can apply mild steroid like dermacort. For the itching antihistaminics like Benadryl or Claritin can be taken.
If the symptoms persist then get it evaluated from a dermatologist and get scabies ruled out.
