Feet that hurt only when standing....hmmmmm.

Have you been to a good podiatrist to check for falling arches,
arthritis spots, sesamoid bone problems, spurs, etc etc?
If your feet hurt more when you are on them, I'd check them out carefully. My feet hurt more in bed, and I've several issues
with them including the PN. That is why you see me offering many solutions, because I've had to try them all!

There are many mechanical issues with the feet and ankles...
This site is just fabulous...you could spend days there really reading all the details!

There are diagnostic help sections to identify problem areas on that site too.

Another thing to consider is magnesium supplements...and/or lotions with magnesium in them.
CVS Epsom lotion ( in CVS stores--ask them to order if you can't find it)

Epsom-IT (slightly more expensive and online)

Kirkman magnesium cream (online only).

When you rub this in...you will find it very very helpful. Doing it regularly will help more.

My magnesium thread:

Magnesium improves blood flow to the extremities and also is important for over 100 other critical functions including your heart, muscles and brain.
