peripheral neuropathy
"I have suffered with peripheral neuropathy in my neck spine for 3 plus years. Started with neck pain and 4 doctors who couldn't diagnose the problem. My 5th doctor who is now my family doctor, put me on 3600 mg of gabapentin a day  and  referred me to a neurosurgeon who found the problem in my neck, surgery was performed to correct the problem plus gabapentin (3600 mg a day), plus other medications I was taking prior to surgery as directed by my new family doctor.
My point being, My symptoms of neck pain, arm pain, and leg pain were initially diagnosed as arthritis by 4 doctors. My family doctor and neurosurgeon in combination with gabapentin, the pain and suffering is now 90% reduced to a livable existence. I am 74 years old."
