Bummer about your injury!

I don't think chiropractors operate on bulging disks.... or do surgeons sell products other than surgery. I am almost positive that any recuperation you might get from your injury will be the result of immediate attention from a physical therapist. Your GP would recommend/refer you for that... I believe. I always take my medical problems to my trusted GP for his advice. Free advice from family, friends, and Internet posts... are worth every penny you pay for them.

With treatment options aside... If something is causing you injury and or pain... stop doing it. I often see elderly cyclists out riding (and I don't mean guys YOUR/OUR age). I spoke to one guy still riding at age 89. I want to be one of those elderly cyclists someday myself. I know that may mean a recumbent or recumbent trike. Honestly... those recumbents look like a lot of fun! Your old bike... may not serve you well in your (coming) old age.

If you were half your age and hadn't had surgery and was complaining of neck pain.... I'd say: get a (bicycle) fitting. And work on core strength, balance, and flexibility. Balance is even more important to our fitness as we age. Not being balanced will make you less flexible... and prone to injury. Without an effort to maintain core strength.... more stress will be placed on "more vulnerable" areas.
