Another more common clinical cause is stones in the urinary system, including stones in the renal pelvis and ureter, and pain in the lower back and abdomen accompanied by vomiting will occur when hydronephrosis occurs. Sometimes it is characterized by pain radiating to the perineum, with frequent and urgent urination, and in severe cases, hematuria, fever, chills, etc. Food poisoning can also lead to symptoms of vomiting and diarrhea. The symptoms of abdominal and lumbar pain, accompanied by vomiting, should be taken seriously and the cause should be investigated in detail at the hospital.
