Hi welcome to Healthcaremagic
The above signs and symptoms suggestive that . there is nerve
compression in the cervical region... hence there is excruciating pain in neck while you are swallowing food.. CT or MRI
will be required to find the site of compression... do not lift heavy weight, do not strain much, sleep on flat surface.. avoid anything causing pain... it will take time to heal by itself,,. analgesic
will be helpful..
Hope I have answered your question..
