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.
Several things may cause numbing in your feet. One cause could be from diabetes. When diabetes is untreated, unrecognized, or undertreated it can cause damage to your nerves. This condition is known as neuropathy. Another cause could come from circulatory problems in your feet. If you are wearing shoes that are too tight, the circulation, or blood flow, to your feet can be decreased. If you have unknown, untreated, or undertreated high blood pressure, this too can cause circulation problems, which could lead to numbness in your feet. If you have any type of decreased flow to or from your feet, numbness in your feet may also arise.
