Used a dental pick not my own to take out a splinter.no visible blood but micro.dried blood possibly.pick used 4-6 hrs prior.hiv possibility?

No: You're almost a grown woman and you need to be aware that casual contact with surfaces that "just might have a bit of dried blood" won't give you HIV. During the old days when there was no Rx, casual family contacts simply didn't catch the virus. Stop worrying about this stuff. You're too smart to end up paralyzed.

Nearly Impossible: I wouldn't worry about it. First, the person using the pick would have to be HIV-positive and have left blood on the instrument. That's unlikely. Then, the HIV virus does not survive well in oxygen, so exposure to air for 4-6 hours would likely kill any virus, if there was any. Then, it was not a needle of hollow-body instrument, so the risk is even lower. And, you didn't stick yourself deeply.
