First, the drugs prescribed are not helpful for nerve damage. It will actually will make it worse. I am currently working with a friend who was given these drugs and she is in terrible shape now. Not to discourage you but she does Liver Flushes every two weeks and it helps her temporarily. She is in a lot of pain and cannot sleep or eat or do any daily duties by her self.
So glad you are not taking those poisons.
What I have learned by reading Dr. Carolyn Dean's book The Magnesium Miracle is that magnesium is essential element in 325 enzymatic reactions in our body. If you find that book in India please read it. Amazon cells it for $10.
