Hello,
For
blurred vision, numbness in arms and concentration difficulty, a
neurologist clinical examination is advised. You may have to under MRI brain and
Cervical spine for ruling out the possible causes.
As you mentioned about the
Bone spur protruding from the upper spine into the brain, I suspect there might be some neurological deficits which may trouble the vision and tingle as well due to compression onto the neurological tissue.
Since you are 55, I will advise for the neurologist opinion and medication followed by that.
Also,
physiotherapy management for the neck and shoulder which will help your RCI and also the Numbness.
Blurred vision will be corrected once the compression of the spur is reduced over the neurological tissue by strength in the muscles.
Hope I have answered your query. Let me know if I can assist you further.
Take care
Regards,
Jay Indravadan Patel, Physical Therapist or Physiotherapist
