Move along that is an irrational thought.
I am afraid that they forget to change the needle after they injected the one before me , because when I got injected , I saw the nurse pick up the needle not from the package , the needle is put on the desk without package ,i am not sure if it is a new one .
Why would you share a needle with someone?
I feel much better after see your reply ,thanks very much !! But still have some question ,If I share one needle with a HIV patient ,can I be infected ? The needle insert into my skin , so I think the needle should have touch the blood , is this an exposure ?
