I'm having horrible muscle cramps and tingling in lips and hands...it started last Friday and has gotten really bad, last night I almost went to the ER it was so bad. I have a check up with my surgeon today and we have to have a good long talk about this...he said with my gastric bypass that it would be tricky with the calcium and vitamin D I am taking 50,000u of Vitamin D daily and those citracal chews ( per day now and also citracal tablets 3 per day) I had high pth levels before surgery and it was tested last week and they don;t have those numbers back now, last friday my calcium level was 8.1 in the hospital it got down to 7.4 and he was worried about seizures. My legs are killing me,,,,last night was horrible and I didn't know what to do. I am taking so much calcium and I have NEVER had cramps like this in my legs, hips and body.....I can't explain it,,,,
