SHARP Throbbing Pain in Outside Edge of Foot
I'm getting a super sharp, stabbing pain in my right foot, just under the ankle on the outside. It comes on suddenly, last for a few seconds, then goes away just as fast. This repeats for four or five times, about a half hour apart but each occurrence getting closer than the last. Then it goes away for a while. When it comes back, usually later that night, they come on much faster until its every few minutes, then it gets to a point where the pain is steady and kind of pulsing/throbbing. The pain winds up a lot less severe but when it starts it drops me to my knees. Ice doesn't seem to stop it, nor does any particular position. This first happened almost a year ago, with one or two occurrences after, then it stopped altogether. Now it happened a couple of weeks ago but not full blown, and now today it is really bad, it has carried over from last evening.
I'm 39 and fairly active and in good shape, I'm on my feet most of the day. Nothing has changed in my daily rituals over the years, and I haven't injured my foot, or put it through excess stress. What could this be?
It doesnt hurt at all to the touch, I think its a nerve issue, maybe coming from my lower back. The area that feels like is being stabbed on the outside edge of my foot is the size of a dime! CRAZY!
