Dizziness, Arm Pain, Fluid In Ear. Diagnosed As Osteochondrosis In Neck. Treatment?

It is already as already 2-3 months that I have dizziness ! It started 3-4 years ago (I am 51 years old). I had one night of dizziness attack after that I was fine thought didn't know the reason. I thought the reason was stress.. Then after 0.5 years I got endless pains in my left arm (later it switched to right arm). It was getting aggravated after physical damage or getting cold. One very experienced doctor after very brief examining told me that I have problem with my nerve on my back.. Then I lost that doctor and had to deal with ones that my insurance provide.. They in 2-3 years still cannot put normal diagnosis - keep saying that I have fluid in my ear (actually I don't) It seems as liquid, I have noise (seashore noise) but it is not liquid. A "NOSE, throat , ear " specialist told me that I don't have fluid in my ear and it would be better if I go and check my neck.. In my MRI scan my Family doctors still unfortunately couldn't figure out anything.. And analyzing all these results I thing that i have osteochondrosys on my neck.. Would greatly appreciate if you could give some suggestions about better diagnosis and treatment. I started my neck exercising , that helps a lot..
Thanks, Elchin
