With administration at a doctor’s office, Botox is injected into 31 sites around the head in a five-to-10-minute procedure. Botox blocks chemical changes on nerve endings thereby reducing migraine pain.
Botox is injected into muscles of the forehead, the side and back of the head, and the neck and shoulders to produce a partial and temporary chemical “denervation” of the muscle to treat chronic migraine. This causes the muscles to be too weak to contract. The dosage to treat chronic migraines is very low.
Effectiveness emerges roughly one week post-injection, peaks around six weeks, and fades around three months. In small doses, Botox is not poisonous to the body. Botulinum toxin inhibits the release of peripheral nociceptive neurotransmitters. The release of peripheral nociceptive neurotransmitters may have a knock-on effect on the central pain processing systems that generate migraine headaches.
The procedure requires not more than 10-15 minutes, and can be performed in a standard examination room. The Botox-A injections raise small bumps over the forehead, but these vanish in within hours and more quickly if ice is applied to the region.
Side effects may include temporary drooping of the eyelid, and flu-like symptoms (diffuse muscle aches, fever, a general feeling of illness). When eyelid droop occurs, the effects reverse within weeks.
Hi,
I just asked my doctor about this and he said that they are using Botox to treat headaches. But they do a series of 31 shots and it is not plesant. It burns. They put them all over your forehead and a few in the back of the head. The doctor I asked was in the chronic pain management clinic at Kaiser Permanente in California. He told me that the patient had to fail two preventative treatments before they would consider this as a treatment.
Another doctor that I had seen previously, a ENT doctor had recommended Botox for tention headaches.
