Botox is injected around pain fibers involved in the creation of headaches. Once injected, it blocks the release of chemicals involved in pain transmission. It can cause a temporary reduction in muscle contractions for up to 3 months, improving migraine frequency and intensity. Small, 30-gauge needles are used to inject the Botox in small amounts in shallow muscles in the skin.
It can take up to six weeks to see the maximum benefit. It may not begin taking maximum effect until the second or third treatment. Patients may see an increasing benefit as they increase in their number of treatments. Many patients see their pain reduced by 50% or more, but this differs by case.
Generally, 10 minutes for the injections.
The most common side effect is a sore neck, in which the patient may use ice to reduce the discomfort. Other serious effects and adverse reactions are rare.
You may resume previous activities unless there are complications. You are cautioned against engaging in strenuous activities. A gradual increase in activities is advised.
