<s>[INST] Recently, Ive noticed these bumps beneath the skin on the inside of my foot, under the arch. Theyre tender to touch or put any pressure on. The only thing I can think of is a recent (maybe a month ago) puncture wound on the same area from a piece of wood. At the time of the wound, it only bled a little so I ignored it and let it heal on its own. Now the arch of my foot is in pain whenever there is too much pressure on it.
