[|Human|] I have had a callus like spot on ball of my foot in middle for years, have done the trimming of it tried pads to keep pressure off it while walking ....basically ive tried it all, not it is really big and thick and it causes me some really bad pain. what should I do? could it be a bone spur in that area of my foot?
[|AI|]  Hello and thanks for consulting Chat Doctor. It could be a callus, but it sounds like you may have a plantar wart. Warts are different from calluses in that they often have a small dot in the middle of them and calluses do not. They are common on the bottom of the foot and can get very thick and painful. If you think it may be a wart, there are two types of over the counter medications you can try. One is a salicylic acid preparation that you apply twice a day (it can take months) and the other is a small instrument that freezes the wart. If you are not sure, see your doctor for a diagnosis. Good luck.
