Re: Losing hope...dizziness gone but vision messed up.
You said the event started when your vision tilted, that could be caused by an aura. An aura can cause any type of visual distortion, including tilting.
However, the continuous vision issues that you mention are not caused by an aura. Almost every confirmed MAV patient I have met experiences some degree of visual problems.
The fact that you experienced a headache proceeded by a visual distortion sounds like a textbook case of classic migraine. Most migraine suffers also say they just want to crawl into bed when their symptoms start, and I find it interesting that this is what you did.
Lastly, you mentioned headache several times during your post, and it sounds like these headaches are somewhat of an interference with life. You need to discuss the possibility of migraine with a physician.
