Sudden sharp stabbing pain in the top of one foot
by Bob F.
(Los Angeles, Ca.)
I'm a 49 yr old male. 5'6" & 165lbs. In very good health. I exercise 3-4 times a week and do good deal of walking as a part of my job.
After several years in absence last night I was revisited by a very familiar pain. Suddenly and without warning I get a sharp stabbing pain dead center in the top of my left foot. It is a world stopping pain. It will last from a second or two to up to a full minute. This comes in episodes ..... last night the pains came once or twice an hour throughout the night. These episodes last from a few hours to several days. Day or night.... morning or evening make no difference.
Years ago I thought it was related to bad shoes. So I bought the best. No effect..... Many doctors & x-rays later it was thought it might be diet related .....a deficiency in potassium. So I ate a banana a day. The results were mixed. Much exercise along with vitamin and mineral supplements were of little help. After a time it simply went away.
Now it has returned. There have been no changes in diet, activity level or anything.
I fear I'll be walking down a hall and simply collapse form this pain out of the blue. What could this be?
I am not trying to pass the buck here but a very sharp pain like you are experiencing is difficult to diagnose without actually examining you.
When people describe sharp stabbing pain the first thought is a Mortons's neuroma. This would occur in the part of the foot just behind the toes, usually the third and fourth toe.
If that is where your pain is then you can read my section on Morton's neuroma, if that is not where the pain is originating from then I think a another visit to a podiatrist would be indicated.
