<s>[INST] yesterday I had toast and juice for breakfast and then lentils with white rice and lettuce salad for lunch. Prior to lunch I suffered a migraine headache, took  some tylenol and it helpped a bit but it left so tired. After eating I got a stomach pain. I thought I ate too much, when I got home I napped and when I woke up I had a very bad stomach ache and my abdomen was swollen. I tossed and turned for a couple of hours until I vomitted. It left me shaking and with a sored lower back and limbs. Today I woke up with a very mild stomach ache but my body feels as if I was ran over by a truck. Specially my legs, it makes it difficult to walk. [/INST] Such a severe pain causing tossing in bed is usually due to ureteric colic. Stone in ureter causes obstruction to urine outflow and smooth muscles in ureter contract excessively to overcome this obstruction & this causes severe pain. In such cases, I advise X-ray KU BU, ultrasound of abdomen, renal function tests, serum amylase & lipase. Empirically I give antispasmodics, painkillers & diuretics. Advise to Chat Doctor. 5 liters of water in 24 hours. Definitive treatment is according to reports. Hope this information is useful to you. Thanks. Regards. </s>
