Fore, I understand the feeling of not being able to do what you used to yet and the suffering (though in different ways). The ringing in my ear seems to have lessened (or I've gotten used to it, but likely both). Did your ENT Dr do balance tests, including laying back and other movements to check any vestibular issues? I would also suggest finding a good Cranial Sacral therapist...it is the best treatment I've had for my head injury...the most helpful of anything so far.
