sorry to have taken so long to get back to you and I hope your surgery went well. By now you must know that the posterior approach to neck surgery is a tough one to recover from...i am about five months out now and am feeling great..but during the first few months the neck and back spasms were pretty tough to deal with. I resumed work about 6 weeks post op..(mywork includes extensive travel) and i did pretty well..
my neurosurgeon..who is a top notch San Fran doc says he isnt quite sure of the laminoplasty yet...the technique is OK but the materials used are still being perfected...he didnt want to do it on me as I am still young (relatively) and active.
I just returned from seeing him for a post op check up and he said the electric shock response from touching my neck was not usual but that he had seen it before. He is suspecting post op swelling and He took me off of physical therapy for the next four months. Now that I have stopped PT, it seems to have helped.
It took four months for me to stop having the pre op symptoms...which was a little disconcerting..I thought they would disappear right away..but each day now I feel I am still improving...
I hope you are happy to be through with the surgery..Keep a positive outlook..you will feel better with each passing week!
