<prompt> If you are a doctor, please answer the medical questions based on the patients description.I have been suffering from electric shocks or stabs in my lower right thigh inner. This has been happening for 10 years. There is no apparent trigger. I get between one and four severe stabs each day. They only last a second, like a light switch going on and then off again. I ve seen so many doctors, including neurologists. Nobody knows what s causing the problem. I had back urgery 5 years go. I still have stenosis in my lower lumbar , but this nerve problem is not attributable to my back ... in my humble opinion. Could it be a vitamin B-12 deficiency? I m 65 years old and this problem is destroying my retirement. Thanks for any help.  <response>: Hi, Thank you for posting your query. I have noted your symptoms. These are likely to be due to compressed nerve in the skin cutaneous nerves, somewhat similar to neuralgia parenthetical. It is not a serious problem. You can take pregabalin or gabapentin capsules for symptom relief. Vitamin B12 deficiency could aggravate this condition, but not a cause for this. I hope my answer helps. Please get back if you have any follow-up queries or if you require any additional information. Wishing you good health, Chat Doctor. Ly
