No, that is not typical after Botox and most likely is due to something else. The Botox usually starts working 1-2 weeks after the injection.
Thank you for the question! The muscles at the base of the neck are numerous and compact. The target muscle that is causing the migraines is very small. I have often wondered if the correct muscle is being injected in the neck or if diffusion has allowed the Botox to affect more than the offending muscle. During migraine decompression surgery, I am able to directly visualize the muscle and dissect the triggering nerve away from it before encasing it in soft fat. I would recommend you seek a migraine surgery specialist in your area if you continue to suffer bad side effects from the injections. Best of luck!
There have been studies done that show relief from migraine headaches in some people.. I have seen this happen but, I fid the results in consistent. Check with your doctor for injection location and dose
