Hi Dear ,
As per your query you have severe pain in neck,arm and numbness on thumb . Well the symptoms you mention in query occur due to may factors like injury , arthritis ,
Osteoporosis , Fibromyalgia , meningitis , stress , anxiety ,
cervical spondylosis , carpel tunnel and sustained one posture for long time like working on computer . I would suggest you to do stretching exercises of arm and neck daily and start
physical therapy of neck and back . Also take ibuprofen or
acetaminophen for pain . Try to avoid stress and anxiety like situation and relax yourself . If condition doesn't get better the conduit orthopedic surgeon again for CT scan and MRI to find out exact cause . Doctor may prescribe
muscle relaxant , ani inflammatory , nerve supplement and particular exercises . Drink warm glass of milk with one spoon turmeric powder in it daily .
Hope your concern has been resolved.
Get Well Soon.
Best Wishes,
Dr. Harry Maheshwari
