Once the flex loosened up and ended, the muscle was extremely sore
, as though I had run 3 miles on that leg alone. It is still sore
now, 3 hours later, to the touch and when walking. It was not a potassium cramp - I injest a minumum of 3 pints of milk every day. Why did this happen? Has this ever happened to anyone else? What could this be sign of? Please help.
