So I woke up this morning feeling fine but as the day went on I noticed my right leg was feeling odd and has stayed that way for the past hour or two. It's like a sore cramped feeling. I'm 25 and sit around when I'm at home but not for hours upon hours. I used to be fairly healthy but have slacked off lately on exercise. I don't recall having a problem like this before. It's around the up back part of my calf to the mid hamstring. It's a warm cramped feeling.
