This sounds like an OCD concern, which is beyond the scope of help that the HIV Anxiety Support group can provide. The OP would be better served in the OCD forum.
Speaking for myself: when i'm out with friends in a club or so (it's quiet hot).
Sometimes ur skin feels like beeing poked, believe me i know what you are going thrue, but there's a big difference between a needle that would poke you and some light skin irritation.
If someone would have sticked you you would haved said: AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
You didn't, didn't you?
you're fine, enjoy life, be happy :)
That it to the HIV Anxiety Support Group.
