Since January, I started to get anxious/depressed, mainly over my future and school. I have been grinding my teeth since I was about 9 or 10 years old, but I only do it during the day. This grinding feels good and its sort of like a relieving feeling. Similar to how I grind my teeth, I also do the same motion with my torso/hips, where I move it back and forth, and it leads to relief. I also have neck and back stiffness regularly. Furthermore, I have experienced muscle twitching since the age of 14/15 but only once a month or so. Now I am 21 and I experience muscle twitching constantly, throughout the day in mostly my legs but also sometimes my arms. Furthermore, I also have begun to have throat problems- not necessairly difficulty swallowing but it just seems like theres something stuck in it. This gets worse throughout the day, where in the morning my throat feels fine but at night its the worse. Lastly, the symptom that has me the most worried is that when I am falling asleep, or in light sleep, I randomly jerk/move my muscles (hand, leg, foot, etc.) causing me to wake up. I have tried to diagnose myself and the most prevalent diagnosis I receive is Huntington's disease. However, no one in my family has ever had this disease from either side. Furthermore I am only 21 and an Indo-Canadian male and the incidence of HD is pretty low in such populations. I am really worried, and need some help figuring out what you guys think I may have. I have been stressed out and unable to function, constantly thinking about this. I have a feeling that the teeth grinding may be a disease of some sort, leading to these symptoms. Sorry for the long post, but I just needed to get all of that off my chest.
