Shouldn't a 'cramp' go away on its own after a while? You seem to be describing something a bit more severe, Lee.
Magnesium - for something acute like this, you might be better served with potent supplements for a few days or a week.
Things I would actually be doing right now if it were me:
- ibuprofen...
runners shouldn't do this, big no-no.
Willie, I remember when I was pregnant I used to get those kind of cramps as the one Lee describes that kind of cramps are actually very comon in pregnant women...oh GOD Lee, I hope you're not expecting
I think a hot bath with epsom's salts would help epsom's salt is high in magnesium.
