Take some time off. Usually 1-2 weeks is appropriate. Inflamation is probably the cause of the pain. If this is the case take about 1,200mg/Ibuprofen a day until the pain subsides some.
You didn't give a lot of details concerning the injury so all I can give is some vague advice.
If you haven't already up your Vitamin C intake to about 2 grams a day, followed by a supplementation of MSM, Glucosamine, and Type II Collagen if you can find it. You can usually find all of these in some sort of joint/tendon support at any supplement shop.
Best of luck in your recovery and don't push it - this will only make things work.
