IF BOTOX doesn't work OR you as a patient do not want to go the route of injections in the forehead, neck, and shoulders, then perhaps the next option would be the newest drug called 'aimovig/ally' which the neurologist can provide information about for you. It is advertised on TV all of the time. This medicine is also a program that allows you to give the medicine to yourself. It's not a scary as the BOTOX and it has good results I am told. I may consider going this route now that I have relocated to a more sunnier location, have fewer migraines and have managed to control my overall health to make the jump. With a new physician that specializes in Migraines, this would be a good time to weigh the pros and cons. Remember, looking at all of the possible ways to control your day to day life and what options you can take to manage it with the best controls is the target here. Evaluating what brought on a migraine will allow you to seek out the cause and the eliminate it to the best of your abilities.
I am glad you were able to re-evaluate your options by talking with your doctor about the effects brought on by the Botox and seeking to change it. That is good communication both for you and for the doctor. Good Job and I know it will continue to help you.
