Get thee to a good clinic. Treatment often involves rest and steroid injections. If that fails, it's knife time.

I would take this opportunity to point out that many of these sort or overuse-type injuries are best dealt with early, but I'm probably the worst offender in the "I'll just ignore the pain and it might go away" club. I broke my ankle playing basketball with a bunch of physicians before work one morning many years ago. I knew that as soon as I took my shoe off I was done walking for the next week or two, so I just kept my shoes on and played for another half-hour.
