Thank you for posting your query.
You have three distinct problems.
First, there is ossified posterior longitudinal ligament
(OPLL) in the cervical region, which has not progressed for more than one decade. This can be left alone, and can be managed with physiotherapy
, cervical collar
Second, there is lumbar disc prolapse
and leg pain & weakness secondary to that. This may require surgery and your symptoms would improve. Your doctor is the best judge regarding surgery, as he has the advantage of examining you, which I do not have.
Third, you probably have osteoarthritis
of the knees. Glucosamine would help in this. You can get further advice on this from an Orthopedic surgeon.
