Botox

Botox injections block certain chemical signals from nerves, mostly signals that cause muscles to contract. The most common use of these injections is to temporarily relax the facial muscles that cause wrinkles in the forehead and around the eyes. Botox injections are also used to treat conditions that affect how the body functions. Examples include:

• Cervical dystonia. In this painful condition, your neck muscles contract involuntarily causing your head to twist or turn into an uncomfortable position.

• Lazy eye. The most common cause of lazy eye is an imbalance in the muscles responsible for positioning the eye.
