my calf muscle cramped and woke me up?
So, this morning at 430am I was woken up by a severe cramp in my right calf muscle. This has happened to me before, but not in almost a year. I tried to get up and walk it off and it hurt so bad I barely made it to the bathroom. I finally went back to sleep and when I woke up, the cramp was all but gone. There is still some achyness in the calf.
What causes this? Could it be the way I was sleeping? It was pretty random though.
