Diagnose the pain in my foot!

Factual Questions
1

Sometimes, while performing very normal activities, I will get a sudden pain in the curve of my left foot. It seems like my foot is frozen- it is dislocated or something, but it isn’t. This pain will gradually increase until it climaxes, and then decreases until it goes away. After that, there is no pain or discomfort whatsoever. I go on doing my normal activities. I say it isn’t dislocated because I feel no snap or click, and it always goes through the exact same procedure- gradual increase, climax, decrease. The whole deal is only abot 10-15 seconds.

I used to get this pain more often-maybe once every one or two weeks. It’s gone away, and it hasn’t happened in maybe 6 months- until 5 minutes ago. I usually stay still and let the pain go away. I don’t try to move my foot because it feels like a bone is going to snap in two if I do. After the incident there are no bumps in my foot and it basically goes back to normal. During the pain, I don’t believe there are any unusual bumps either. The pain is under my foot, right where the curve in the inside of my left foot is.

Does anyone have any idea what this could be? It hasn’t posed any problems but I’d like to know if it will. And it’s really painful!

It’s a cramp. I get them too, sometimes. I’ve heard that it may be exacerbated by a potassium deficiency, but I’ve found no confirmation for this.

It sure sounds like a cramp. I can also attest to the potassium deficiency link to cramps, as well. My girlfriend used to get cramps in her feet and legs, all the time. She was taking large calcium supplements, and her diet didn’t include enough potassium to balance it. When I explained this to her, and she added potassium to her ever-expanding array of supplements, the cramps went away. Purely anecdotal, but highly convincing to those who lived through it.

It is also widely recognized by the medical community, as well.
