Hi I have pain under my left ribcage area. I suspected spleen but my doc checked me out last week and said that it was likely a pulled muscle. I never pulled a muscle! The constant pain has been getting worse since I saw him. It kills me to cough or sneeze and even hurts to stand up straight or take a deep breath. I think I should go back to the doctor because I m not buying the pulled muscle theory. There aer no other symptoms except possibly sweating. What should I do? Thanks.
