For the past couple of days I've been having leg cramps
, and i get a tingling sensation all through out my body. Somtimes, some of my toes, only one my left foot feels a bit numb. Last night, I took a calcium supplement, 1200 iu, and almost a minute later, I felt a burning sensation all throughout my legs, it felt like my legs were on fire it was so bad, I've never felt this before, ever, especially after taking my calcium supplement. I still feel it, a day later. what is this?
