I have neuropathy bad so I am up most nights searching on the internet. My latest searching shows very little. My first question does anyone know of a study with everyday Cialis, it is basicly a vasodilator and is not neuropathy basically the lack of blood flow too the nerves. Hence better blood flow to the extremities hopefully repairing the nerves. My second question does anyone know of any studies being done with Testosterone and pain. I know that when a man gets older he looses most of his Testosterone but I have heard that if that man has pain for whatever reason and is given Testosterone the pain is at least decreased. I have also heard that this treatment works for woman as well.
These's are thoughts that go through my little pea brain, maybe someone can add too them or shot them down whichever.

This link has a discussion about improving circulation to the feet and lower legs:

The drug discussed there mostly is nifedipine (which also dilates blood vessels).

Before you think about drugs, do consider magnesium supplements. You can also soak in the epsom salts which have magnesium. Diabetics lose magnesium from the kidneys daily, so have a major deficit in it. By replacing it you may not need anything further. The basic responses to the Rebuilder I think come from the magnesium salts you put in that foot bath!

There was a discussion on our RSD forum not too long ago about testosterone/ pain. If you put "testosterone" into the search in the upper right of the index page there, you'll find it and perhaps others.

Yes, there is much information on this and other adrenal hormones.
