For about a year I have had diffuse, symmetrical
tendon pain. The pain is mainly in my elbows (both Lateral and medial epicondylitis) and the back of my knees. But it also afflicts my left rotator cuff, the area just below both calves, the base of the achilles, my knees, and (within the last 6 weeks) has started to affect my fingers and toes. Along with the tendon pain, I experience a lot of muscle stiffness in my forearms, hamstrings, and calves
The pain is very activity related.
