question: hello. while showering this A.M. I notices a dime sized soft lump or bump located on the inside of my right foot centered between the bunion bone and the heel, It is ever so slightly sensitive to the touch. You can press it in, not fluid-like, but soft. It almost looks like it could be a large bug bite. I have been wearing non supportive shoes lately. I am on my feet all day as a teacher. weigh 117 pds, 5 4 tall, 53 years old. I did walk a great deal this past weekend wearing good supportive sneakers. Do you have a clue?
