I just took my first injection of enantat qv 250. I don't know if I did something wrong or what, but I have a huge knot on the area of the shot that goes about 4 inches all the way around my thigh. Every time I stand on my feet for any amount of time, it feels like it's on fire and hurts like hell. I have been trying to stay off of it. But I was onit almost all day yesterday and my leg was swollen all the way down to my ankle. I really don't want to go to the dr. But I'm starting to get worried. It has been about a week and it is not gettig any better. Any suggestions.
