So this wednesday i injected 1 ml of hg sust into my left ass cheek. Now it's sore, there's a knot under my skin about the size of my thumb. It does not seem to be swollen outside. I have no fever. It's maybe a little hot to touch, but not much just painful, sore and a bit bothersome, that's all. What should i do? Let it be or massage? And i know if it gets bigger or i get a fever i have to go to the doc. Any productive ideas and opinions are welcome.
PS. This is the first time this has happened to me in six years!
