Relax and visit a doc if it persists. 5wks is probably nothing compared to your drinking time. It takes a bit to 'heal'. My calves were sore as hell around 5wks..I linked it back to low on vitamins(pottassium) from my drinking/diet. Pretty sure I was also kinda sleep 'spasming' the first several weeks. I started taking a multi-vitamin and some other OTC crap. LOL
