Hi welcome to Health care magic forum.
Thanks for calling H.C.M.F.
You can have full faith upon me regarding the answer.
You have pain in rt and lt ribs, Between the chest and stomach.There is pain between the shoulder blades, You have sharp pain
between the ribs when you press, that is called tenderness ,and it suggests the location of the problem at that place.
Appendex is an organ present at right lower place of the stomach, so don't worry about appendicitis
Your problem appears to be peptic ulcer
, gall bladder
problem , or pancriatitis.
I advise you to consult a gastro enterologist, for diagnosis and treatment. You may need to have GASTROSCOPY, C.T.scan of whole abdomen besides other routine tests for confermation.
Wishing for a quick recovery. You can have your doubts cleared if necessory.
