hi, thank you for providing the brief history of you. a Thorough examination of the lungs and musculoskeletal assessment is advised. As post abdominal surgery this is the common symptom patients have. For which the steam inhalation and physical therapy is advised. Since post surgery breathing exercises helps improve the capacity of pure blood for optimum healing and strengthening of the abdominal muscles as well. in my clinical practice I have been working on cases with post gall bladder surgery. and breathing exercises work well on them and early recovery is attained. regards Jay Indravadan Patel
