hi. noted history of laparoscopic cholecystectomy and recent postoperative site pain associated with trauma. are you experiencing any other sign or symptom (such as fever, nausea, vomiting, bleeding)? if there s none, observation will do for now. cold compress over the area might also help decrease the inflammation or swelling. there s presence/progressions of symptoms, a follow-up consult with your surgeon is best for physical examination and clinical evaluation. even those who have been operated on several years ago, occasionally experience, discomfort or mild-moderate pain over the operative site area, but is tolerable and resolves spontaneously. dignostics (such as imaging) and management (medical and/or surgical if indications are found) will be directed accordingly. hope this helps. good day!! ~dr.kaye
