What is the prognosis of a person who has Stenosis?

A few months back i was diagnosed with having stenosis of the neck.I am currently in PT three times per week,doing traction and excersises to strenghth neck,also been getting nerve blocks every month and a half.C-5 and c-6 are pintched,however thinking other nerves on right side being effected,as they too are starting to get pain running down the arm and hand along with numbness.Is there a cure for this,or is this part of the degenerative process?How long will it take before it effects me to the point of not being able to do normal tasks i do everyday?
