For the past 6 months I've had a lump / cyst on the bottom of one foot in the arch area. When I get pedicure's it tends to go down in size. But once I've walked for long periods of time it aggravates it. I know that as a child I had to have about 5-7 big splinters removed from this foot (from a wooden ladder in salt water). My question is there a cure for this or should I have it drained / removed?
