Im in my 7th week of Q. V. 250. 2cc a week i bumped it up a half a cc and injected in my shoulder. It didnt get any sorer than usual but swolled up a lot and got a real hard knot in it about an inch down my arm from my point of injection. most of the swelling has went down but the knot is still there it feels like it is loosing up some but now its getting really red. Its only been about 5 days should i be worried. maybe it was just to big a shot and will go away. Most all the soreness has went away but the knot scares me any suggestions execpt not to shoot that much in my shoulder again.
