Symptoms of leg tendinitis

The main manifestation of the disease is involvement of the rhabdomus of the proximal extremities, and symmetrical weakness of the proximal extremities is the characteristic of the disease.

When the muscle atrophy, the muscle fibers degenerate and harden, and there is a sense of flexibility when touching it. Most patients have myalgia, which can be spontaneous pain, exercise pain or tenderness. When there is generalized myositis, swelling, weakness and myalgia of the affected muscles are obvious. Rare outbreak of myositis, can cause rhabdomyolysis, a large number of myoglobinuria, resulting in renal failure.
