I'm sorry to hear you're experiencing lower abdominal pain along with vomiting. These symptoms can be caused by various conditions, some of which may require urgent medical attention.

Here’s what you should do:

• Seek immediate medical evaluation: Since the pain has lasted for several hours and is accompanied by vomiting, it is important to see a doctor promptly to determine the cause. Conditions like appendicitis, bowel obstruction, or infections can present this way and may need urgent treatment.
• Avoid eating or drinking large amounts: Until evaluated, it’s best to avoid solid foods and large fluids to prevent worsening nausea or vomiting.
• Note any other symptoms: If you develop fever, severe pain, dizziness, inability to keep fluids down, or blood in vomit or stool, seek emergency care immediately.
• Contact emergency services if symptoms worsen: Use the emergency number provided if you experience severe worsening or new symptoms.

Please consult a general surgeon or an emergency medicine specialist as soon as possible for a thorough assessment and appropriate management.
