Willie I get the migraines from back pain all the time, (my injury is in the lower back) I get it mostly from that new hot needle thing now on my upper back that I was asking about a few months ago, which btw I tried a bunch of stuff (chiropractor, PT, yoga, accupuncture etc) I'm currently working with my PT on strengthening the upper back muscles but it hasn't really helped. Idk about pixelated vision but I get a head rush, not quite a dizzy feeling but sort of I guess & my vision darkens sometimes when I stand up while my knees feel like jell-o, the best way to describe it is my brain feels like it's losing reception with the rest of my body... If I stand still & steady myself it'll go away shortly, the Dr's haven't been able to figure that one out but I think it has to do with my weight loss thing. I'd def get yours checked though just to make sure.
I also have really bad tinnitus but my gf is really understanding of it, like how I have to have the TV on literally all the time & while we sleep, & how I Bluetooth podcasts while I'm taking a shower in the morning while she's trying to sleep in the next room (for some reason shower/rain etc is most unbearable for me). She does nag me about other things ofc but never that, if it's loud enough to disturb the neighbors & I don't realize she'll just turn it down herself.
I don't do the polite nodding thing anymore though I just do a blank stare, if someone wants to get my attention they know how to do it. What I really love though is when someone is talking quietly & I'm missing like 50% of the words, especially when I obviously don't hear them & they walk up & tap me on the shoulder to get my attention & start speaking in a whisper... I go, sorry you're going to have to speak up, & each time they increase the volume of their voice by 1%, like 8 times.
btw it's still raining here I got a pic of the lightning while we were out getting freyon for my gf's car.
