hi. noted history of right sided abdominal pain, subcostal area. yes, it is possible that you have a gallbladder pathology (most commonly gallstones). costochondritis and pleuritic chest pain must also be ruled-out. it is best if you consult with a doctor, preferably a general surgeon, for physical examination and clinical evaluation. diagnostics (ultrasound, complete blood count, liver function tests, etc.) and management (medical and/or surgical if indications are found) will be directed accordingly. if it is indeed of gallstone disease, definitive treatment is cholecystectomy or surgical removal of the gallbladder. if it is not an emergent case, based on ultrasound and clinical evaluation, an elective cholecystectomy after giving birth will be advised accordingly. it can be done laparoscopically (goldstandard) or thru open technique. low fat diet is also recommended. hope this helps. good day!! ~dr.kaye
