Botox - What if I decide to stop the injections?

Yes you can stop the injections. You will not have the benefits that you got from Botox when you stop getting the injections. However, I stopped getting Botox after several years. The doctor told me that people who had gotten Botox for a period of time, did not have the same intensity of pain that they had had before Botox. That was very true for me. My migraines were better and the spasticity in my stroke foot which was almost intolerable before Botox was far better after having Botox.
Although extremely unlikely, Botox can cause serious side effects that you should contact your doctor right away. Also allergic reactions can occur occasionally which should be reported right away. Select your doctor carefully. It's important that injections be placed precisely in order to avoid side effects. Botox therapy can be dangerous if it's administered incorrectly. Plus there are conditions that you should not get Botox. Your doctor will know which ones.
But Botox can greatly help conditions such as migraines more than 15 days a month, cervical dystonia where neck muscles contract involuntarily causing head to twist or turn into an uncomfortable position, some neurological conditions, such as cerebral palsy, that can cause limbs to pull in toward your center, excessive sweating, bladder dysfunction and more. So it can be worthwhile to get Botox to treat these painful conditions.
Talk to your doctor to get all of your questions answered before you start Botox. If your doctor doesn't know, find another doctor.
