Hello,
Stenosis is a medical term, which means Narrowing of the canal in the neck region, this is what guess your problem is (as you did not mentioned in the history whether it's stenosis of cervical canal or some other thing).
As you said above, By profession you are an ORCHESTRA CONDUCTOR so be careful about your movements of Neck.
Based on the symptoms you are giving in the history it looks to be a severe narrowing that is compression the nerves which are running out to limb, so because is the
Tingling and
Numbness sensation in the arm.
I suggest that you take care of your health as a first priority, if land up for any permanent damages to the nerve, then it will affect your hands nerve supply and also the sensation and motor activity.
Regarding the surgery, yes if the Stenosis (Narrowing) is severe then one need to get operated, there will be definitely risk associated with the surgery, Despite an Expert Neuro Surgeon there is possibility of damages to the surrounding blood vessels and nerves.
But there is no other option rather taking the risk. So, please plan for the surgery as early possible.
Hope I have answered your query. Let me know if I can assist you further.

Dr. Mohammed Abdullah
