In my opinion i don't think the cervical problem of your father spine is the main reason of that kind of persistent vomiting but sometimes the painkillers or medications used to treat the spondylitis pain could cause such side effects on chronic use.  I suggest he maintains a high fluid intake to flush his system, stop any kind of treatment and take the antivomiting and avoid high cholesterol and salty meals and make some lab investigations to rule the underlying cause of vomiting for proper evaluation and management.
