Welcome to HCM,
You should have mentioned ENT related symptoms also for which you consulted two ENT specialists.
These type of symptoms can be due to increased intracranial pressure also.
You should first get your eyes examined by Eye specialist for intraocular pressure
Please get your BP checked and if retinoscopy shows any signs of increase in intracranial pressure, get CT scan of your brain done.
In case of normal reports,you can consult an Orthopaedic surgeon
and get your cervical portion examined.
Meanwhile you can take analgesic
anti-inflammatory with muscle relaxant
tablets twice daily under medical supervision.
With good wishes,
