Botox relieves migraine headaches and other painful conditions, such as sciatica, neuralgias and neck pain.  A recent study of 43 patients with arthritis of the shoulder suggests that Botox may relieve arthritis pain as well.  This was a double-blind study where half of the patients were given Botox and the other half saline injections.  Neither the doctor nor the patient knew what was being injected.  The results clearly favored Botox and the difference was statistically significant.  This adds another possible indication to a long list of conditions that Botox might relieve.  The safety of Botox in this study was as remarkble as in all previous studies, which now number in hundreds.
