Deductible medical expenses are expenses to diagnose, treat or cure a disease or condition that affects the natural function of the body or mind. Expenses that are of general health benefit are not deductible.
Chiropractic services are allowed, provided the chiropractor is treating a disease or condition affecting the natural function of the body, and not just for general health benefits. Massage is more of a problem, it would have to be prescribed by your doctor or chiropractor to treat a specific disease or condition.
