If you have both abdominal pain
specially if it is in the upper central part along with
back pain then it could be a referred pain
from stomach. Get yourself checked with
gastroentrologist. Alternatively you can have ocid ( omeperazole ) 20 mgs with domperidone
both twice a day and see if it relieves your pain. If this doesn't help you than you need to see orthopaedic surgeon
