I am a 22 year old female. I have recently noticed 3 smalls bumps on the inside of my left ankle. They are soft, they do not move, they are painless, and flesh-colored. The largest "bump" is about the size of a dime. The funny thing is, these bumps are visible only when I extend my ankle outwards. If I push on them I feel nothing, and when my leg is not extended I cannot feel anything in the spots where they are located. They are not currently affecting anything except for my peace of mind, but any ideas about what they could be?
