<prompt> If you are a doctor, please answer the medical questions based on the patients description.Doctor, I have been feeling a lot of pain in my upper and lower abdomen for the past few days. Can you tell me what might be causing it?  <response>: Its possible that you have sustained an injury to your abdomen. The pain in both upper and lower abdomen is common in such cases. I would recommend getting an ultrasound or CT scan to confirm the diagnosis.
