I am taking 50mg of Winny every other day using a 28ga 1" syringe and have noticed that one it causes some pretty severe pain for the next several days. The other day I injected high and to the left on my glute and now I have a baseball size knot that is pretty painful and is slightly feverish. Is this normal or did I do something wrong. I used to be an EMT and have gotten pretty good at self injection so I know my method of insertion is sound. Any information would be appreciated.
