Chestnut. thank you so much. I'll tell my friend that you are going to ask your neurophysiologist.
At last I have spoken to my consultant neurologist and asked her directly whether a circulation booster can damage the nerves in the legs and feet of someone with peripheral neuropathy.
She said very clearly it would not damage the nerves and there is no reason why you shouldn't try one. They are designed to improve lower leg circulation and reduce swelling, but may have no effect on the neuropathy. It's also possible that the neuropathy may cause the electrical waves to be painful, in which case you would stop using it or turn down the intensity.
