Rhabdomyolysis is the breakdown of damaged skeletal muscle. Muscle breakdown causes the release of myoglobin into the bloodstream. Myoglobin is the protein that stores oxygen in your muscles. If you have too much myoglobin in your blood, it can cause kidney damage. About 26,000 cases of rhabdomyolysis are reported in the United States each year.
Cause of Supination. Supination occurs as the foot tilts to the outside. Supination is the rolling of the foot to the outside during normal walking or running motions. The term is usually used in connection with over-supination, which means that the arch of the foot is too high and too much weight is placed on the outside of the foot.
I assume that both your feet are swollen. This is important to note because new swelling in just one foot can be caused by a blood clot in the leg or by an injury to the foot or ankle. When both feet are swollen, the cause is almost always fluid retention in the legs. The most common reason for swelling in both feet is incompetent valves in the leg veins. The leg veins return blood to the heart after the blood has delivered oxygen and nutrients to the foot and lower leg.
