Thanks for your quick reply.
My 3.5" is much shorter than your 8", scary.
Me too tried all sorts of lotions and Elmore oil, vitamin E oil, Chinese rubbing oil, infrared, TEN. The only thing which helps a bit is Vitamin B12, but it only improved the condition from "very sore" to "a bit sore" for the first two weeks, no more improvement afterwards.
I just came back from my follow up appointment with my surgeon. He said that the incision went through the upper skin and then the ligament in the middle, not through the muscle under the skin. He said it could be the nerve between the vertebrae bone and muscle, which was injured when the muscle was separated from the bone during surgery. 90% of patient takes 6 months to recover and it could takes up to 18 months.
I just hope it will not be there forever. I will try acupuncture next.
I will talk to my PT for neck strengthen exercise again, not just message.
I think my muscle problem is weakness and fatigue and sensitivity problem is cause by nerve, hopefully not the spine again.
