Late last week my roommate was complaining about a spot in his back hurting, I kept checking, but nothing was there, yet, when I ran my fingers over and pressed a certain area he said it hurt. Sunday a rash appeared in that spot that looks like poison ivy, but he hasn't been around any and it doesn't itch. He says it hurts, and we asked the pharmacist and got some cream for it. The pharmacist thinks it's a bug bite, but we have no idea what could have bit him, or if we should be more concerned. Does anyone have any ideas?
