I've Been Experiencing Weird Sensations For The Better Part Of

I've been experiencing weird sensations for the better part of a year. I should mention that I took a pretty significant fall about 3 years ago and hit my head, but felt fine after even though I chipped a tooth. After about a year I developed a pretty stiff and sore neck and the left side, so much that I couldn't turn my head to the right. That eventually went away after a month or two. A year later is when everything went sideways. After a brief run on the treadmill I noticed a stiffness in my left butt cheek, so I stopped and started to stretch it out. I noticed that my left leg had weird sensations going down my inner thigh and it was becoming difficult to walk or run. I put even more weight on it to balance out the weight. I started loosing even more sensation in my leg, but it was still functional. It felt like all the muscles had been pressed backwards. It was shortly thereafter that I started experiencing diarrhea and felt like I was losing control over my bowels. Thankfully this only lasted for a few weeks. After that i was at my girlfriends house having sexual intercourse when I lost sensation in the left side of my penis and scrotum. This went on for weeks and it was causing urinary retention where I had to constantly go to the bathroom but barely anything came out. And when I did get a flow going it still felt like I had urine still in my bladder afterwards. In January I was at work with my feet up on the desk playing a competitive game on my phone when all of a sudden I felt and heard a snapping in the left side of my body (I'm convinced now that this snap was in my head /neck) which caused everything on the left side of my body to contract. All my muscles were extremely tight, but after 2 weeks the started to loosen again. I also had really bad pain above my left eye and felt my teeth were being pulled. But I wasn't feeling right. I went to my doctor and had xrays from my waist down and found that I had constipation and a bit of arthritis in my lower back. I was sent home and stated putting more fiber into my diet. It was extremely difficult passing a bowel movement when I was able to, otherwise I would go days without having one. Sitting had become difficult as I would constantly move in my seat to find a different position. I was ok when I was active, but when I sat it was sore on my butt cheek. I went back to my doctor and he did a full panel CBC blood panel and everything came back fine. I also went to an ENT for the little stiffness I still had in my neck and the constant clogging in my ear and all my tests came back fine. My doctor sent me to an osteopath and had some work done with the osteopath until one of our sessions caused sensations starting to happen in the right side of my body, starting in the leg and waist, like the left side. I stopped seeing him after that and was at a complete loss. I was also fighting with my girlfriend a lot and I was starting to get anxious around her. I eventually found another osteopath and he took a more hands on approach than the last one. He fixed a few issues with my posture and allowed me to breath a bit better than what I was able to do. It's been months since then and my doctor diagnosed me with anxiety and I have been seeing a Neorpsychologist. I was also given CBD oil to help with the anxiety. I also just recently had a CT scan for my abdominal and pelvic area, because of the blood in my stool and the pain that I still experience in my lower back. However there feels like something in my head has separated and my breathing is the worst it's ever been and I have dulled sensitivity all over my body now. I find when I breath properly some sensation comes back. I feel like I've been split open from my spin from head to toe and feel like an elastic band that exists from the center of my head down to the center of my pelvic area has separated entirely making me feel like there's been a separation right down the center of my body. And a few months ago because I was breathing poorly (probably inverted) it felt like something was crawling up my backside until it got to my skull at which point it felt like the roof of my mouth had so much pressure pushing against it that something felt like it broke and I had the worst pain in the roof of my mouth and was digging for days afterwards. I am convinced that I ruined a vital support structure in my head. Now my jaw and cheeks hurt an the time. Please someone, help me with what is happening to me.
