Do Botox injections really work for hemifacial spasm?
Temporarily, yes. An injection of botulinum toxin (Botox) causes a small, partial paralysis of the muscle and stops the spasm. The paralysis is temporary, so injections need to be repeated approximately every six months. See more about Diagnosing and Treating Hemifacial Spasm.

How did I get carotid occlusive disease?
Your arteries most likely became narrowed or blocked due to the buildup of atherosclerotic plaque in your blood vessels. That plaque buildup often occurs as a result of high cholesterol, high blood pressure, heart disease, diabetes, smoking, or obesity. Carotid occlusive disease also has a family component, so having a family history of stroke increases your own risk of having carotid stenosis or carotid occlusion.

How is hemifacial spasm treated?
Injections of botulinum toxin (Botox) can provide temporary relief, but the permanent solution is usually microdecompression surgery. See more about Diagnosing and Treating Hemifacial Spasm.
