Gallbladder inflammation generally presents as sudden severe pain in the upper right abdomen, typically occurring after consuming a large amount of fatty foods or most frequently at night. The pain may radiate to the right shoulder or back, indicating gallbladder inflammation. For treatment, antispasmodic pain relief medications can be used. If these are ineffective, opiates like pethidine may be employed to alleviate symptoms. Additionally, it is necessary to perform routine blood tests and imaging, such as an abdominal CT scan or ultrasound, to confirm the diagnosis. Once the diagnosis is confirmed, aggressive anti-inflammatory treatment should be pursued. (Medication should be used under the guidance of a physician.)
