The main symptoms of cholecystitis include pain in the upper right abdomen and fever. If this occurs, applying heat to the painful area may temporarily relieve the pain, but it is merely a symptomatic treatment and not a cure, as cholecystitis is caused by an infection and requires antibiotic treatment. Therefore, the fundamental treatment is to reduce inflammation. Merely using heat for relief does not address the root of the disease. Thus, it is essential to receive treatment in a hospital, where a doctor can prescribe medication, which is the most effective and fundamental method.
