Well, that IS interesting. Looks like there may have been a few misdiagnoses then which isn’t surprising as there are many shared and overlapping symptoms particularly with the early stages of VM. At least with VH a test will prove whether or not a misalignment exists, it’s either there or it isn’t. There’s no conclusive test to establish migraine. It’s just a case of ruling out common obvious other possibilities as far as possible, hoping to find some definite history of migraine and then seeing if the preventatives work.
With the similarity of symptoms I do wonder about the definition ‘dizziness’, that means different things to different people. True, spinning rotary ‘dizziness’ is ‘vertigo’ (either the room or yr body appears to spin), ‘dizziness’ is non-rotary, whoozy, light headedness. They do say true vertigo causes migraine. Don’t know whether VH would cause that. Maybe true vertigo might be an indicator.
Glad yr nausea stopped. Adjustments in prisms can be required, that’s an ongoing process. Initially sometimes they are upped in steps so your brain can adjust. Of course there can also be deficiencies between the prism required by the severity of the alignment and the actual maximum amount of prism your brain will tolerate. As the years go by too larger prisms can be needed to produce the same effect.
With my case I was feeling dizzy and much research was done (by eye experts, not me) into whether my eye misalignment was the cause, despite the prisms and I was assured not. It was much later and with worsening symptoms that I was introduced to the MAV syndrome. Do let me know how you progress or if you hear anything else relevant. Remember, I’ve a vested interest, too.
