My SD was Dec 19 and so far so good, but I noticed the other day that my left calf started to hurt. It felt like I had a huge Charlie horse but I never did..just the soreness..it's been two days now and when I woke up this morning it was really sore to walk on..I didn't think to much of it till I noticed the tenderness hasn't gone away. Is it possible I could of had a cramp while I slept that didn't wake me? Or should I call my dr.? Ty
