The first thing that should be done is an ultrasound examination of the abdomen when there is vague pain in the right lower abdomen. This is because some patients with appendicitis may present with pain in the right lower abdomen and attacks with nausea and vomiting, especially if they have a history of acute appendicitis attacks. Patients with chronic appendicitis may also have acute attacks after exertion and may require surgery if necessary. Some patients have ureteral stones, which can cause pain radiating to the right side of the groin and even painful urination, frequency, urgency and fever. The pain caused by the ureter is also associated with nausea and vomiting. During the acute attack, pain medication can be given, such as intramuscular pethidine hydrochloride injection or pindecoxin injection.
