Hi Ahlex,
Thank you for sharing your story with us. Good to hear you've seen your doctor regarding this, but I wonder if another conversation about what the goal of taking propranolol is, other than reduced migraine attacks. Propranolol, brand name Inderal, a beta blocker, is used for migraine prevention, in fact it was one of the first medications FDA approved for it. You can read more about this medication here; https://migraine.com/?s=Inderal&submit=Go.
Vestibular migraine can have a wide range of symptoms including balance issues. However, NOT having balance issues doesn't necessarily rule it out. This link has loads of information on this type of migraine disease; https://migraine.com/?s=vestibular+migraine&submit=Go.
There are many different supplements that can be taken for migraine attack prevention, but it's important to talk to your doctor before taking anything over-the-counter. Many think dietary supplements are natural and safe, but that's not the case. Supplements can interact with medications, and/or other diseases. When you get a moment you may want to look at our section on supplements here; https://migraine.com/migraine-treatment/natural-remedies/.
I wish I could give you a definitive answer on whether or not you have this type of migraine, but only a qualified doctor can do that. If you're not happy with him, there is no harm in getting a second opinion.
Hope this helps,
Nancy
