neuralgia
"I had lumbar decompression surgery in July for a herniated disk (L4,L5) and spinal stenosis.  A week after the surgery, the nerve in my left leg and foot "woke" up and the pain was severe.  My left foot was constantly burning, with feelings of electric shock 24 hours a day. I couldn't wear my shoe and I was very depressed by the pain - I couldn't walk  barely without pain.  My surgeon put me on Lyrica and within a week, almost all of the burning disappeared.  I get a random "shock" in my toes, a spasm in my arch and part of my foot is still numb, but I can function again.  The pain is manageable and minor.  I'm told it will heal but will take months. I've had some blurred vision, but that's better than the pain.  Lyrica was a life saver."
