Relapsing
So see that a relapse lasts a day or days to be considered a relapse but I've never had it last that long. I usually just had to rest for a few hours and then was better more or less. For me that was the problem because I was very stubborn and had shit to do so maybe I didn't notice it as a problem till it stated (permanently) taking my walking away and the diagnosis took a little too long to get treated. I'm really wondering if anyone else experiences relapse like this where it only lasted a few hours to recover?

It's usually a flare up, when your symptoms come and go. After a few hours of rest or a good nights sleep, I usually feel better (I also take amitriptilyne to help with pain relief and sleep through the night). The last time I had a relapse (they called it a Pseudo relapse at the hospital), I was unable to walk, open my eyes, have any tolerance to light, my speech was slurred, my vision all over the place. They put me on antibiotics via drip and the recovery slowly started. But back to your point... it's usually considered a flare up when your symptoms come and go.
