Hi Dear,
Welcome to HCM.
Understanding your concern. As per your query you have severe pain in the neck post an injury in the site of surgery . Well there can be many reasons for symptoms you mention in query like muscle spasm ,
cervical spondylosis, TMJ problem , nerve compression , ear infection or heart problem like angina . The symptoms can also occur due to residual infection of surgery or trauma caused during the surgery .
Consult ENT specialist for proper examination. For now stay calm , take ibuprofen and arm , do light stretching exercises under expert or acetaminophen for pain and take proper rest. Doctor may also refer you to
dentist for TMJ problem . I would suggest you to consult orthopedic surgeon for proper examination and treatment . Doctor may order CT scan , MRI along with nerve conduction test and physical examination to confirm the diagnosis . Doctor may prescribe
muscle relaxant , anti inflammatory , nerve supplement along with
physical therapy . In some cases doctor may recommend surgery .
Hope your concern has been resolved.
Get Well Soon.
Best Wishes,
Dr. Harry Maheshwari
