about four days ago i had some muscle pain after working out. today i woke up with two clusters of painful red dots on my thigh. i also have larger red dots in my pubic hair that have scabbed over, and are much more painful. are these two things related? i'm not sexually active, so i don't think the dots are anything like that, but could i have contracted herpies or something another way? or could it be crabs? my medical knowledge is pretty limited.
