cervical dystonia
"I suffered for years from neck pain thinking I had problems with a disc.  Three years ago I developed a tremor in my head, a no-no type of movement.  My PCP said I had essential tremor so again I put off going to a doc who knew what he was talking about.  I decided suddenly to see a neurologist and so thankful I did.  Diagnosed properly and then the Botox which is wonderful.  I would say the pain is gone 100% and doesn't even start to come back until about the tenth week after.  Tremor has greatly decreased and I feel like myself again!!! Happy and so grateful."
