Botox injections are noted primarily for the ability to reduce the appearance of facial wrinkles. They’re also used to treat conditions such as neck spasms (cervical dystonia), excessive sweating (hyperhidrosis), an overactive bladder and lazy eye. Botox injections may also help prevent chronic migraines. Botox injections use a toxin called onobotulinumtoxinA to temporarily prevent a muscle from moving. This toxin is produced by the microbe that causes botulism, a type of food poisoning.
Why it’s done? 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, Lazy eye, Muscle contractures, Hyperhidrosis, Chronic migraine, Bladder dysfunction, and Eye twitching.
Risk: Botox injections are relatively safe when performed by an experienced doctor. Possible side effects and complications include, Pain, swelling or bruising at the injection site, Headache or flu-like symptoms, Droopy eyelid or cockeyed eyebrows, Crooked smile or drooling, and Eye dryness or excessive tearing.
