Where is it? Elbows?
Here's what worked for me:
Aleve, not Advil.
Rest it! No gripping.
Massage the area with a golf/tennis ball- hard! You'll find tender spots.
Take a naked ice cube and rub it where you've been having pain.
Took about 2 weeks for mine to go away with all of these treatments.
Tried to get rid of mine for months and couldn't until I added the ice cube and tennis/golf balls.
