Buy a bottle of Comfrey oil and just rub it into the injured area twice a day. Comfrey's thought to have healing qualities.

I was skeptical at first, but I use it often now, and have noticed an improvement in my tendons. Whether that's because of the Comfrey oil I don't know, but a bottle doesn't cost much. If nothing else it'll improve blood flow to the area, speeding up healing.
