Cholecystitis usually does not cause hidden pain in the two ribs, but usually pain in the right upper abdomen. Cholecystitis refers to the acute and chronic inflammatory reaction in the gallbladder caused by gallbladder stones or other causes, and is a common digestive disease, which can be categorized into acute cholecystitis and chronic cholecystitis according to the urgency of the disease. Acute cholecystitis is characterized by acute onset, persistent and paroxysmal pain, usually in the right upper abdomen, and when the pain is severe, it will radiate to the right shoulder and back. In chronic cholecystitis, the pain is usually in the epigastric region when the patient has a full meal or eats greasy food, and can also involve the right shoulder and back, but it is rare to have hidden pain in the ribs. Occult pain in both ribs may be associated with other causes, such as costochondritis and pleurisy. If the patient has hidden pain in both ribs, it is recommended that the patient seek medical attention to clarify the cause of the condition and treat it aggressively.
