callus on tip of big toe

I have done some anatomy reading as the discomfort prompted me too understand what I am trying to describe.

When I wiggle my big toe with my foot in plantarflexions, I get cracking in the toe and feel it vibrate far up my leg. One concern is how the tip of big toe is 'always' needing to be filed caue it 'builds up'. I have been to MD and zero fungus...but no other info.

The inside of my right ankle has two prominant bumps; (a) medial malleolus and (b) one is two fingers distance anterior to medial malleolus. My left ankle does not have both bumps, (b) is missing. I often get pain under my right med mall and often poke around in there with my fingers without thinking, it hurts, but feels good, hmm.

Thanks you so very much for any advice or information.
