Positive thoughts
Yes, I need to emphasize that my friend had pain that was constant and getting gradually worse, AND he had a lump that was visibly growing. He was a very tough guy but it got so bad, he could barely walk. This doesn't seem to be the OPs situation at all. I would just give it a few more weeks to heal, these sorts of injuries can take many months to completely go away.

PS. Why did I say that he "WAS"? He still is, 10 years later doing great. Even a relatively grim diagnosis like this doesn't have to be a death sentence.
