Can nerve damage be corrected? i've been having all symptoms of nerve damage in my legs, & left arm. what r the treatments cuz i'm terrified. thanks!

Possibly: There are many causes of neuropathy some of which are reversible ( for example: significant hypothyroidism can be associated with neuropathies which can resolve with thyroid replacement Rx). The same is true for certain vitamin deficiency states. You should consider seeing a Neurologist to determine what type of neuropathy you have/What's causing it/what therapy could help.
