Although the statement holds some truth, it is only partially correct. Think of your nervous system as two distinct sections:
your central nervous system (CNS) and your peripheral nerves. The CNS includes your brain and spinal cord. Your peripheral nerves are bundles of nerve fibers, in area such has your hands and feet, that carry information to and from your spinal cord; think telephone lines.
Now, in the event of brain or spinal chord damage, nerve regeneration rarely occurs as the CNS has a very limited capacity to heal. However, peripheral nerves have quite an amazing capacity for regeneration and work in just the same way that a persons finger would were it to be cut off. If the finger is reattached without too much time having passed, the nerves can regrow and the person will have a complete, or nearly complete, recovery in most cases. This concept is similar to how our treatments are able to regenerate these amazing peripheral nerves that have been affected by your neuropathy.
Because Neuropathy is a progressive condition, it does more nerve damage each and every day. So, just as if that person with the severed finger waited too long to go to the hospital, there can come a point where your neuropathy has caused too much damage leaving no further options for us to help you. For these reasons, if you want to prevent any more serious damage to your hands or feet, we always stress the importance of catching this and doing what’s necessary as quickly as possible.
