Hello i'm writing this message regarding a problem i'm facing recently. A sharp glass piece pierced into my left feet sole for about 4 years ago. After taking medication it came out at that time. But suddenly few weeks back I felt pain there and got medical checkup again, did usg and x-ray. Now, usg predicting that there may be some tiny (?) piece of foreign body but x-ray didn't find any. I visited a general surgeon he just gave me a course of antibiotics concerning the matter as foot corn. But pain is same as it starts over the month. In such a situation, what should I do now? Please suggest.
