I woke up at 2am(as usual), but my calf hurt like I had a charlie horse and it wouldn't go away. I still have it. I told my OH about it and he said to call the doctor, make sure I don't have a calcium deficiency and see if they could give me anything for it. So, I did. Now they have really got me worked up. They want to look at my leg and check for blood clots. My cousin and uncle have both had clots in their legs, and I remember them talking about it. I was under the impression that clots in your legs are extremely painful. Mine is only a dull ache unless I'm walking or flexing my foot upward. Should I be worried?? I know they are serious.
