I have been using injections for sometime now and never a problem. yesterday I did 50ml of winny with a 23g needle to my thigh. all of a sudden it started to sting pretty bad but i figured that i was in i might as well finish. a few seconds after i pulled the needle out it started to sting pretty damn bad for about 2 hours.
when i woke up this moring i noticed that it was still stinging and their was a huge bruse. any one ever had that happen before and any advice on how not to do it again. thanks
