About 4 days ago I noticed that a rash was developing on both of my upper posterior arms. It has now started spreading down on to my forearms, and soon after I noticed it on my upper arms it appeared on both anterior thighs, and has spread down my shins. The rash is rather generalized over arms and legs, pinpoint bumps that are normal skin-colored (no redness). They do not hurt, no drainage or pustules have developed, but I do have mild itching. I don't have allergies or excema, psoraisis, or other medical conditions that I'm aware of. Do you have any idea what it might be? Any suggestions would be appreciated. Thanks.
