Although Botox is best known as an anti-wrinkle jab, in 2015, half of
its sales were for non-cosmetic uses, including excessive sweating, where
it blocks the nerves that supply sweat glands. It’s also good for controlling
incontinence and easing migraines.
Botox has also been found, in several small trials, to relieve
back pain for up to four months in about 60% of patients.
