I am struck by the "hammertoe" comment.

This often results from muscles in the calf that do no relax properly, and
are stiff and pull the tendons. My podiatrist looked at my feet years ago..
and said off hand..."I can fix those surgically for you". $$ in his eyes!

Switching to a wider shoe, helped me alot. But what really helps is
magnesium. You might try some daily epsom salt foot baths. This will allow
your feet to absorb the magnesium and relax those spastic toes.

If it works for you in any way...improving feeling, or reducing pain, I'd start
oral magnesium as soon as possible. I have a magnesium thread on
our Vitamin forum here, that goes into detail. Many people do not get the RDA for this mineral, and our muscles/tendons and bones suffer as a result.

Needless to say, I don't have those hammertoes anymore, either.
