Ive been paranoid since about everything that touch me or goes in my body. now im stressing i got my blood drawn it stung and now im sick. i hope they didnt give me hiv. going to order a 4th gen test?

Blood drawing can occasionally hit a nearby nerve ending causing it to sting more than usual. The equipment used is sterile/single use only with needles discarded after use. You don't get HIV that way, although you could if a drug user with aids reused one of their needles to inject you. The risk for you to get HIV or anything else from the usual blood draw is zero. Test if you want.

If you wish to directly deal with your emotional reactions, would urge proactively seek counseling. Have found a combination of Cognitive-Behavioral Therapy and Biofeedback could prompt confidence and relaxation in the face of medical issues.
