One month back went to pvp movie theatre and there I felt some prick pain but then I checked my seat thoroughly with hand but did not find any thing but after that incident I read in internet that people are placing hiv needles in movie theatre seats I also found very small superficial scratch on my thumb I dnt know how it happened. I just want to know is this a significant exposure to hiv im worrying too much and unable to sleep or eat properly from that incident im assuming every incident as a potential threat of hiv and constantly worrying I had full panel body tests few days before that incident and im not having any disease please help is a test warranted.
