Revitive will probably do no harm (unless you have lymphoedema in your legs, in which case it might) but it works on the veins and blood flow. Peripheral neuropathy is damage to the nerves. Peripheral nerves send sensory information back to the brain and spinal cord, such as a message that the feet are cold. Peripheral nerves also carry signals from the brain and spinal cord to the muscles to generate movement. Damage to the peripheral nervous system interferes with these connections. Like static on a telephone line, peripheral neuropathy distorts and sometimes interrupts messages between the brain and spinal cord and the rest of the body. So we end up with cold or numb feet, prickling, feeling like you are wearing three pairs of thick socks or walking on a mattress (my particular favourite!). Sometimes also pain. As far as I can tell, the nerves can repair over a period (uncertain) of time, which is good as the damage seems at least in part reversible. Stimulus, massage may also help the nerves but it seems really hard to find out what actually, really does. Most advice is about controlling pain and not tripping!! .
