I have a knot on the lateral side of my left knee. Very tender with palpation. Increased pain when crossing my legs while sitting. If I wake with my knee bent straightening it is a 8/10 pain. I have attempted ice massage, phono/iontophoresis with dexamethasone, e-stim, stretching (ITB,hamstring,calf) and moist heat. Minimal decrease in pain. Knot still present. Any ideas?
