<s>[INST] Hi, I m feeling pain under my right rib cage for 3, 4 days now. It s not very strong but it is there. I m a bit worried because I was partying for two weeks and drank a lot, so I m worried that it could be something with my liver. But otherwise I drink rarely, is it possible that liver reacts so quick? Could it be something else? [/INST] Than for using Chat Doctor .as per given history it may be muscular pain. Have u other symptoms like fever, vomiting, headache, feeling weakness then it could be liver related problems, u have no any symptom above then don't worry it may be muscular pain use muscle relaxant Chat Doctor. I am sure u get relief in 7 days. Hope u r satisfy with these answered.u have any problem write back to me, I would like to help u.regards </s>
