Botox Isn't Just Cosmetic.
Botox has some medical uses in addition to cosmetic ones. Injections can treat chronic migraine, overactive bladder, crossed eyes, severe sweating and various conditions that affect the muscles.
A condition such as cervical dystonia causes involuntary muscle contractions. Botox, once injected into the affected muscles, reduces or gets rid of the spasms. Someone receiving treatment for chronic migraine would be subject to 31 injections on the head and neck area, while someone with urinary incontinence issues would have the toxin injected into the bladder wall.
The effects are temporary, lasting from three to 10 months, depending on the condition.
