Try adding the homeopathic remedy Belladonna 30c 3 pellets 3 times a day for 3 days and let me know how things are going.

Hi critterkids,

As you likely know already, there are a myriad of causes that manifest in migraine and vertigo. Makes for difficult diagnosis. A quick suggestion for you to try.

Type into your favorite search engine "ear crystals".

Obviously, I don't know if this will be relevant to your situation in any way or not, but it could spare you both a lot of time and undue suffering.

Ear crystals are well known in ear/nose/throat medical circles, but often ignored and left untreated. Shameful!
