Hi,dr. Last night,I went shopping for an overcoat for my kid,while I was in the shop ,I found a cute overcoat, I touched and felt it,but suddenly I felt pain in my hand,it was the clothing pin in front of the clothes that pricked my finger,I didn't find any tiny wound,so I fail to press the wound,and there is no blood ,either.but i am quite sure I was pricked by the pin, when went back home I use alcohol to clean my hand, I didn't feel the pain, and I looked carefully for the wound this morning,i found a very very tiny red spot,I still not sure if it was caused last night.since it was weekend there were a lot of people in the shopping center , I am not sure if it prick anyone seconds before me and if someone was pricked shortly before I was pricked(less than 5second)and he/she was HIV positive,will I have the risk of getting HIV this way? Is there anyone around the world who got HIV in this case? I am really freaking out! Help me dr.
