Hi there, I'm 25 years old female I recently noticed that my arm is being incredibly shaky and jerky while pushing stuff away with the thumb in certain positions. I even made a video of it and it's disturbing. Not just that, I have muscle fasciculations for more than a year already that comes and goes occasionally, mostly in arms, hip muscles, abdominal voluntary muscles and sometimes low back muscles. I don't know if there anything to do with, but I also got loud clicks in every joint in the body, including the distal ulno radial joint, elbow joints, and mostly shoulder, knee and ankle joints. From time to time it is hard for me to stabilize myself, and I feel clumsy a bit. If it is possible I would like to attach the video of a shaking hand here somewhere. I didn't check those with a doctor though. Any thoughts?
