I have developed an area of pain, less that dime sized, about a half inch under my small toe on the bottom of my right foot. It is slighly raised, and appears to have a small white center. It is not any softer than any other spot near that area of my foot, in fact the "head" of the spot seems dryer and a bit rougher. There is no visible discharge. At any rate, it pains me when pressure is applied on the spot, and throbs for a short time after getting off my feet at the end of the day.
Any ideas what it may be ?
