I’ve got bulging disc at I believe was C4-C6 same as you I’ve been to audiologist everything is good for my hearing but the tinnitus is so loud I’m going in for an evaluation for hearing aids to try quieting the sound in my ear down so I can sleep. When I quit work a year ago working nights I would wear a blue tooth mask and play music to try overriding the sound that I’ve had since about 1996 from an air blast to my ear but has got worse since my surgery in Back Surgery in April. I’ve not had double vision but was getting a flash in the corner of my left eye. Then about 2 months detached the vitreous gel in my right eye. I’ve got a cyst on the brain but neurologist says it’s not causing any problems.
