I've had tinnitus since age 19, but it went away after a while. Came back after the TBI. For weeks, my left ear has felt plugged.
Could be earwax buildup- earplugs at night? TMJD affecting the ear (jaw problem). I'll try a Q-tip this weekend. If that doesn't help, wax removal kit.
I really hope everyone's problems get solved somehow.
Getting fed up with the human body.
