I woke up with only one of my fingers being slightly numb. It feels like it fell asleep, but its lasting much longer. I'm not sure if its a blood clot, although my mother says it isn't. I'm 16, 6'1", and i weigh 170 lbs if that's any help. I read they often start in the legs, and are misinterpreted as cramps. After my fitness testing for phys. ed., i wouldn't know because of the pain from all the running. Any help would be greatly appreciated.
