For the past 2 years, my head, or even by brain, have been feeling these strange sensations and I don't exactly know what's causing it. I don't if a sore neck before has caused it to be this way, because when it started, I get weird headaches and shortly after that, My brain felt like it's been getting dripped with water and get the feeling of being dried off after that. My eyes (after a month or two) also started to feel weird, as if I couldn't move my eyes, even though I could. It just felt way heavier and more awkward to move them around. In june/july, my brain started to feel like it's on ice, and didn't even eat anything cold, it just happened. That sensation occurred for a while on and off, and lately, it feels weird, like I can't exactly describe this feeling. I feels stuck, but loose, but also uncontrollable. I'm not sure if it's connected to it as well, but a specific part of my back (around the left should blade) has been feeling weird. no pain, just weird. I just want some explanation, or even some clarification on what it could be.
Forgot to mention, as when it started, it felt like my ears had liquid that needed to be cleared out, but there was no liquid when I felt my ear canal.
