There are many reasons for deep breathing pain on the right side of the stomach. If the pain is in the upper right abdomen, you need to pay attention to whether there is pleurisy or gastrointestinal problems such as gastritis or colitis, which usually result in abnormal stools, such as diarrhea or nausea and vomiting. If it is an inflammation of the pleura, it may also be accompanied by symptoms such as coughing, coughing up sputum and breathlessness. The pain in the right side of the abdomen should also be considered if appendicitis, gallbladder stones or cholecystitis is present, which needs to be confirmed by abdominal ultrasound or CT at the hospital. It may also be a problem of the genitourinary system such as kidney stones, ureteral stones, prostatitis, etc. These diseases are usually accompanied by hematuria or difficulty in urination. If it is a problem of this type, a detailed examination, lithotripsy or other treatment is needed to confirm the specific condition and provide targeted treatment.
