Please rephrase this question. You said, you "found on the arm has a pinhole". What does that mean?
I mean I have probably been needle injection of the virus
Seek professional help for your phobias.
I'm sorry to ask this question, if there is blood was pouring into my body, have risk? Or blood in the needle force lost activity
Come on man, you know damn well there was no "blood pouring" into your body! You're being completely irrational and paranoid. Your problem is mental not related to HIV. Find a psychiatrist to discuss your irrational phobias and leave the HIV forum to people who actually had a risk.
