So I stretched my leg out this a.m. while in bed and felt a pain in my calf that made me jump out of bed. I grabbed my calf and felt a tightened knot in my calf. After a minute or so the initial pain subsided and the bump was gone. But all day I have had a dull pain in my calf. If I stretch my leg out and move my ankle around I still feel soreness. I have only had a charley horse once or twice in my life. Is that normal for a charley horse or could it be something more serious like a blood clot? After googleing some stuff I am freaking myself out.
