I had cervical spine surgery 1 year ago C4 C5 disk replacement and C4 C5 C6 fusion from an injury 11 years ago, I also have rsd/crps II in the right upper extremity. S/P surgery in have had problems with my voice, it is slowly getting better. I have burning in my neck, the back pain is the same and now I have intermittant blurred vision and I have noticed some hearing problems increasing over the past year, I cannot hear someone speak to me when there is a lot of back ground noise
Hello, I would explain that the hearing loss is not related to the surgery but probably related to an inner ear disorder or the head trauma.  For this reason, I recommend consulting with an ENT specialist and performing a physical exam and an audio gram. Regarding the burning in your neck, I would recommend taking pregabalin or Gabapentin.  You should discuss with your doctor on the above tests and treatment options.  Hope I have answered your query. Let me know if I can assist you further. Take care Chat Doctor.
