Hi, I ve been going through some troubles lately. After I got my wisdom teeth removed, I had a feeling of a bug crawling around the back of my mouth when smoking, even a little bit. When not smoking, it felt like a lump in the back of my throat. It was so bad that I would often reach in the back of my mouth to grab at this bug, but always found nothing, even after digging around for minutes. It drove me insane. About a month after my wisdom teeth removal, I had a thc concentrate, and I started going rally insane. During the time, I couldn t drink water, I had an extremely difficult time swallowing it, and when it went down, I threw up immediately. I have genetically low blood pressure, so I tried salt, as that gas always been a remedy for me when I get nauseous. I threw up right after trying to swallow the salt, not too mention it tasted absolutely disgusting (salt usually isn t bad at all for me). I threw up multiple times this night and it was the WORST experience of my life, and I ve had a lot of medical problems. Now, about half a year later, I still have the lump in the back of my throat, but the bug feeling is gone. Now, there s more problems. A few weeks ago, when laying in bed at night with my eyes closed, my whole vision flashed white, and my ears were ringing. When I got out of this state, I felt like I couldn t tell the amount of time that elapsed, it could ve been one second or hours. I felt like my whole brain was flash-banged . When I looked at my phone it was only a couple minutes later. When I rub from my jaw line (right side) to my cheek bone, my right eye flashed a bunch of black spots in my vision. At night, I see things. When other people are driving I often see dark-shadowy people in the road walking. Bushes can be dogs or deer, mailboxes can be people, everything can be anything. It s progressively gotten worse, to the point where I don t drive at night anymore. This isn t as bad when I m in the lit up city, it s mostly in neighborhoods and poorly lit areas. I will often (at least once an hour) just daze off while listening to other people conversate. I like to call it a power-trip . I will go off into my memories, sometimes years old, and I will relive it. I ll be recalling everything the other people said, and what I said. When this happens to me, I will keep going over different, but relating, memories over and over again until someone snaps me out of it. I feel like this has been getting worse with age, but I can t tell for sure. I ve been feeling like I m going crazy, and I m only 20 years old.
