People with leg pain related to back problems had more short-term relief if they received chiropractic care along with exercise and advice, rather than exercise and advice alone, a new study from the Annals of Internal Medicine has found.
A researcher was quoted as saying “This of course, must be considered in light of alternatives for this condition, such as epidural steroid injections or surgery, which are not only much more costly but also associated with important (and serious) adverse events,”.
