Previous bad experience with botox, wondering if i should try again
While some people do have a slight headache following Botox treatments, it typically lasts a couple of days. I would be very cautious to have Botox again. Be sure your doctor knows your history; maybe try a lesser dose.
Botox and headaches
Botox is FDA approved to treat migraines, however it can also cause headaches usually just immediately after injection and for a day or so, and its rare. It could certainly happen again, so I would proceed with caution. You could talk to your doctor and try a lower dose. Discuss it with your doctor and or get a second opinion.
Botox and Headaches
Botox is now approved to treat migraines. It is not a typical side effect for a headache to last more than a few days. I suggest you go to a neurologist who is experienced in Botox to get an opinion. Botox is great from an aesthetic point of view but a headache lasting four months should be pursued.
Botulinum toxins...can be a pain in the head (for some people)
Thats a great question and anyone who uses these medications regularly will tell you it is probably one of the more common concerns and or/side effects. In fact, apart from slight discomfort, redness around the injection site and minor bruising, headaches are the most common side effect of neuromodulators.
However, it is not common to have the headaches last 3-4 months. Most people find as the muscles become altered due to the neuromodulator, the get some discomfort. This typically resolves. I have, however, seen a few people describe what you noticed. I think your description above is spot-op with respect to muscular overcompensation. You end up getting "tension headaches" as other muscles try to pull and oppose those muscles that are altered.
Based on my experience, this resolves eventually. I certainly can not guarantee it, but I would talk to a physician with experience with these medications in person and see what they think. I'd review your medical history to ensure there are no other concerns.
I hope this helps
