I don't know how this is possible, but my friend thinks he developed an infection over two months after his last injection. Its a grape type bump under his skin that is where his injection site was that is slightly painful when you push on it. He wants to get it checked out but he's in the military so is afraid to go to the Dr. If he goes to an ER and pays cash or something like that, will he be ok? Or will the military find out about it?
