I had my body  move front and back slightly while i sit(especially when leaning forward) and stand still. And i had issues like my jaw muscles tightening but no tmj pain. And i remember having stiff hands when playing odd or even and feeling uncomfortable. So i did a vitamin b12 test it came out 625 pg/ml But i had mecoblend tablet with 1500 mcg methylcobalamin 10 hours before test so i have doubt whether it affect my b12 result and should i take b12 supplements or check for other issues I had previously taken b12 for 10 days 3-4 weeks while I had stiff traps and i had jaw tightness and it solved my issues and had tinnitus 6 months back and now also I have low levels of tinnitus I also sneeze daily
