I see a chiropractor occasionally to adjust my upper back and neck. A good chiropractor can help problems that most doctors will only drug.
I know many elderly people with fragile bones do see chiropractors, so there is no reason thal patients can't also see a chiropractor. Just make sure you explain your condition and the nature of your bones in advance.
I would also suggest asking friends and associates to refer you to a good chiropractor.
