Anyone know what's wrong with my toe? It intermitently gets very tender and red.

Left pic = left foot/bad toe. Right pic = right foot normal toe reversed for comparison.

I'm a doctor myself I just don't know what's going on with it.

Posted this in the other thread but should have posted here.
Im a doctor and need help diagnosing what's wrong with my toe.
It's been swelling over the last 3 years getting progressively bigger and redder, slightly tender to touch but if I knock it it gets very painful. Starting to throb at night when I'm in bed. It hasn't bothered me before but now I can't walk barefoot anymore without it starting to hurt.

Affected toe on the left and my normal right foot (mirrored image) for comparison.
