Last week I did a shot of ice in the big vein that runs over my bicep, about .2 g. I pulled back and drew some blood to make sure I was in, which I was, and slowly pushed it in. I waited for the rush, and... nothing. I've missed before and know that it burns like hell when you do, but nothing this time, no rush, no burn, just nothing. It was pretty disappointing because it was the last of what I had. About a minute later, I noticed a big bump that formed at the injection site but no visible bruising or rash, etc. Its been over a week and, although the bump has gotten smaller, it is still there. You can't see it, but you can feel it if you run your fingers over it. Still no visible bruising or rash or anything else. It is is a little tender if you push directly on it but other than that it doesn't hurt. I am pretty sure I didn't miss since I got the blood and it did not burn and the fact that it didn't feel like it did the one time I've missed before. I know it was good stuff because of the two shots I did before this one. Does anyone have any ideas on what happened? Thanks.
