Right Side Deterioration

I am a 50 year old male with good health, no diabetes, do not drink alcohol, smoke, drugs, etc. I walk, hike, run, take OTC multivitamins, antioxidants, B-Vitamins, etc. I am in good shape and not overweight. I do regular low-impact exercises, at home. I have never had any injuries, at all.
I have had lower back issues in the past, and I had an L5/S1 laminectomy about ten years ago. No problems since, although I am noticing some ‘movement’ in that area again. While a concern, it doesn’t cause any extreme pain, and is remediable.
Over the past year I have a general pain and deterioration of the right side of my body. It starts at the base of the skull, and goes all the way down to the underside of my right foot. Starting at the top, I wake up with dull headaches, that last all day, I have intense pain at the base of my skull, right Eustachian tube issues (they vibrate when I sleep, causing me to wake up and turn over to my right side), right shoulder pain, right neck pain, right hip pain, and intense right plantar pain (fasciitis?). The latter was very intense the other night, in my sleep, that it caused me a general lack of sleep.
I have always (since childhood) noticed that the right side of my body has been problematic, with poorer vision in my right eye and hearing in my right ear.
Now, at this age, I am more concerned, and things seem to be deteriorating.  
My work involves sitting at a desk, although I am very conscious of the issues surrounding that, and I stretch and strengthen as best I can.
Stretching seems to work best, but it has limitations. Heating pads don’t seem to relieve any symptoms, especially in my neck, but they are comforting.
Any help would be appreciated.
I have not seen a doctor about this, since it seems like an ‘ill-defined’ issue.
