Health-care providers may recommend the classic RICE treatment for tendonitis. This is a four-step process of resting the joint that is in pain, applying ice packs to it, compressing the area with an elastic bandage, and keeping the joint elevated, as explained by the University of Rochester Medical Center.
Over-the-counter pain medications such as aspirin or ibuprofen may also be recommended. With approval from a health-care provider, the muscles around the sore joint can be lightly exercised within a day or two, according to the University of Rochester Medical Center. Stretching is also an important aspect of treatment for tendonitis.
