The treatment for cervical spondylosis
depends mainly upon the sign and symptoms of the patient.
It can vary from simple physical therapy
in the form of excercise and massage therapy
to taking pain killer drugs to kill the pain and ultimately to surgery.
Now it is important to make the correct choice depending upon the symptom and its severity. If it is not that much severe than it is good that you continue with the physio and yoga
under the monitoring of a physiotherapist and can have some pain killers depending on requirement. But is symptom is severe and not imporving with all this than you may require surgery to get over this problem.
Thanks and take care.
