Hello. For the past month or so, I've been having a sudden, sharp, stabbing pain in the bottom of my foot. It's always in my right foot, and always in the same spot, on the bottom of the ball of my foot. It doesn't really feel like a cramp, and I can move my toes freely when it happens, my muscles don't tense up. It's just a really sharp, strong pain. It goes away after about 10 seconds. And it happens at least once a day, up to 3 or 4 times per day. Is this normal or should I see a doctor? Should I be concerned about a blood clot or something?
