Any help that can be given is appreciated! I started the hcg injections a week and 1 day ago. On Wednesday after starting, my left hip suddenly started feeling painful and I had to walk with a slight limp, couldn't easily cross my legs. It has progressively gotten worse. Last night I was in extreme pain. I can barely walk and sitting down is also painful. I read that it could mean I need magnesium and potassium. I took two tablets before bed, but woke up in pain still. I've lost 7pounds, but am stopping now because I'm not sure if the hcg injections are the cause. Has anyone else experienced this? Planning on going in to the emergency room once my kids are at school.
