<s>[INST] I am a 23 y/o male who just since yesterday night progressing to today and has been much worse today has had left lower abdoimnal pains. I thought it was just cramps or gas but it hurts when move, sit, stand and espically cough, it also hurts when i lie down. I didnt feel like running right to the ER so i am looking for some advice, and if maybe i should still wait to see if its gas or something. My stool has been normal yesterday, unknown for today. [/INST] Hello, welcome to the Chat Doctor.BRIEF.it could be infection or stoneDETAIL. Since from your history the pain could be more likely because of infection, stone in the kidney or just because of gas. Even if you feel some swelling during coughing then it could be because of hernia. Until you get checked by doctor, you may have painkiller tablet (Tuscan)at home and have light food like soft rice and plenty of water. For ruling out the cause you should get ultrasound abdomen ang x-ray PUB done and discuss further. Hopefully my answer will be helpful. Chat Doctor.  </s>
