If you respond to the epsom salts, do them once a day for at least a week. The magnesium in them opens up small blood vessels to improve circulation there and also they block pain signals from the NMDA pain receptors.

It is safe, inexpensive and easy to use epsom salts as a soak, as long as you don't use hot water.

Look at what you are eating. Too much sugar or carbs, or MSG in processed food (including restaurant food), or histamine containing foods can cause nerve problems for some people.
Some react to hot sauces which are nightshades. Avoid hot sauces, chilis , paprika for 2 weeks if you eat them alot. You might be surprised at the improvements you may have.

There is a histamine thread in the subforum at the PN forum here. Search "histamine" on page one there and I have some links you can read.
