The patient presents with pain in the right back and under the right chest, mainly due to acute cholecystitis. In this case, an ultrasound examination of the gallbladder can be performed at the hospital to clarify the diagnosis. If the pain is caused by cholecystitis, it is recommended that symptomatic treatment must be given in a timely manner, and if necessary, anti-inflammatory and cholagogic tablets can be taken for treatment. If cholecystitis is more serious and the patient has unbearable pain, it is recommended to use laparoscopic surgery to remove the gallbladder in time, which can effectively relieve the pain. If the pain occurs in the chest and back at the same time, it is recommended to go to the hospital for lung cancer related examination. For example, lung CT or lung MRI, etc. can be used for clear examination and diagnosis. After clear diagnosis, it is necessary to decide whether to take surgery and other treatments according to the patient’s specific condition.
