I have a rash that itches on my hands and lower arms and a few on my upper legs. They come up as tiny red dots with a white pin head center. They then seem to spread out a little and the while goes away. I have had it since mid April. Not sure how to get rid of it or what it is. I put sprays on it that is for itch, bug bites, ivy poison etc. I did see a doctor and he said it looked like dermatitis. He gave me a script for a steroid but it raised my blood pressure too high so I only took it for one day......six pills. He said to stop taking it but did not recommend anything else. Any suggestions ?
