I have pimple like rash on upper left arm, down to my elbow. It seems to get a bit better with antifungal and hydracortizone creams. Possiblities?

Staph infection. At worst, if they are real red pustules, they could be a topical staph infection. If they are skin colored small bumps, and you have a few on the other arm in the same place, it's a genetic condition called "hyperkeratosis pilaris". Creams help temporarily but do not cure or remove it. You may need to have somebody look at it to tell the difference.
