HIV rash?? Long post

Hey ladies, does anyone have experience with hiv rash? I've looked up pictures of a rash that I just broke out in and it was showing really extreme cases. I feel like what I have looks more like hives, but the two seem to look really similar to what I've found. Can anyone give me some more information on this? Im always really paranoid when it comes to stuff like this and would really like some insight. Ive not had unprotected vaginal sex but have had oral sex without a condom. I don't feel like the people I associated with had HIV, we discussed diseases/infections but it's still not fool proof I know. I've not really had symptoms along with this except being tired,(which isn't anything new or changed). I'm just paranoid and I plan on trying to find somewhere to get tested asap just for peace of mind either way but can someone give me some info on what it looks like/difference between this rash and hives in the mean time?? Thank you so much. Please don't be negative to me, I'm just looking for some insight!
