I've what I'm pretty sure is test rash on my bicep. I took a prop shot there 3 days ago and this morning I noticed a light red rash. It's about 4 inches long, along the belly of the muscle, and 3 inches wide covering both heads. Is this test rash? How long does test rash last because I like to keep my shirt off around the house and don't want to have to answer my roomates questions.
