KGO-TV, ABC7 Anchor Pete Wilson. Bay Area TV anchor and radio talk show host Pete Wilson â whose local broadcast career spanned three decades â died after suffering a heart attack during hip replacement surgery at Stanford Hospital, KGO-AM radio officials confirmed Saturday.
Most of us have experienced an occasional charley horse, that sudden, intense muscle pain that grips the calf muscle. Many people have, inexplicably, felt this pain in the middle of the night. Unfortunately, there is as yet no clear explanation of why it occurs.
The cramp, or charley horse, is due to the muscle contracting (shortening and tightening) in a sudden and violent way. These nocturnal leg cramps usually occur in the calf muscle. But foot and leg cramps do happen at night also. Cramps in the thighs are less common. One main reason for the pain is because blood flow to the muscle is restricted. Waste products also build up within the muscle tissue.
