So a buddy of mine (this really is a buddy of mine) has a problem and we talked today about it. He told me what was going on and I told him we should go to the forums because I have had some good advice from some mishaps of my own. So he is injecting an oxy 40 today and notices a small bit of pain during the shot but didn't quit. He drew back and got blood and everything seemed fine. He noticed that he really didn't feel the shot all that much but and it didn't really hurt right afterwards. So a few hours later he said he noticed a very slight lump but there was this deep aching dull pain which at the site and he is noticing some nervy type pain which pops up in ramdon places on his arm and even in his elbow. It is aching pretty badly and hw is slightly worried. I told him not to worry it was probably just a miss but he said it didn't feel like any other misses. He said it was super tender but you couldn't tell anything by looking at it. What do you guys think is going on? was I right about the miss- I am not all that knowledgeable when it comes to this? should he be worried about the pretty bad pain? The shot was on the top of his arm about halfway between his elbow and wrist. If it was just a miss are there any immediate dangers. I wish I knew more so I could guide him.
