Botox injections have been tried for the management of back and neck pain, as well as headaches. Botox is a poison that can paralyze nerves. The theory behind using Botox as back and neck pain medicine is that it interrupts the signals that go from nerves to muscles, and increases range of motion (ROM).
Despite the increase in popularity of this treatment, no convincing evidence of its effectiveness has been found. In fact, the Cochrane Collaboration, an independent organization that reviews medical literature to learn about the validity of treatments, noted that Botox injections appear to be no better than injections of saline solution for decreasing pain or disability due to mechanical neck disorders. And, in a physician review of medical literature, meant to help guide doctors' practices, Botox was not recommended as a treatment of chronic pain.
In the hands of the wrong person, Botox can have devastating effects on the nervous system. This is because, until it is properly diluted and prepared, it remains poisionous. If Botox is used as a treatment for back or neck pain, it should be administered by a licensed medical doctor with experience working with the substance as a medicine.
As with anything on the market, it is important to be aware of potentially unscrupulous and/or inept medical care. About's Headache site has more information on that, exposing the dangers of Fake Botox injections that cost 2 people their lives.
