I just found out there are two very small pieces of rubber floating in my test, it maybe because I'm using a huge 19 gauge pin to draw and then switching to a tiny 23g to inject. I'm really worried about it because I'm already half way through and at this point I have no idea if I accidentally injected some of that in my muscles. My question is if that could happen your body will find a way to reject it or it'll cause an infection or so, thanks for your time.
