<s>[INST] Last night, I had sudden stomach and lower abdomen. I have never experienced the pain before, and it was almost unbearable. I started to become dizzy and thought that I would faint. The pain worsened when I tried to move, go to the toilet and stand up. This morning, my stomach still aches, but the pain is not as severe. [/INST] Hi, thank you for posting. I have gone through your query and I understand your concerns. Based on what you refer I can say that you suffer from colonopathy. To treat this disease you should take proton pump inhibitor medications. But, before starting the treatment you should confirm the diagnosis. To do that you need liver function test, abdominal ultrasound, complete blood count and urine test. Consult your gastroenterologist. Take care. </s>
