How long will a needle mark remain on the skin? Assume the worst case scenario- syringe with used (dull) needle. What is the maximum possible time the puncture 'hole' will be visible on the skin?
Also, will a dull needle leave a hole on the skin similar to a bug bite hole?
Guys this is really important for me. Please.
Thanks in advance.
P.S: I'm not looking to shoot up drugs. I just want to know.
