<s>[INST] I have severe pain in the  left side of my abdomen and up under breast bone that last for several days.I am a 39 year old female. The pain came on gradually but got worse through out the day. I feel better when laying on my right side. Today I had a small bowel movement with out even knowing I was doing it and I don't have diareah. I have never done this before. [/INST] Hi, thank you for posting!I have gone through your query and I understand your concerns.Based on what you have said above, I think that you might suffer from IBS (Irritable Bowel Syndrome). It is a disease that affects bowels without any known cause and often it is developed in people with anxiety disorders. In order to improve you health condition, you should follow these guidelines: 1-avoid spicy and acidic foods2-don't drink alcoholic and carbonated drinks, coffee, milk3-reduce the amount of carbohydrates you take4-eat high fiber foodsIn order to confirm the diagnosis, you need an abdominal ultrasound, a liver function test and a complete blood count.The treatment of this condition is a little bit complex so you need to consult your gastroenterologist. I hope this answer is helpful to you. Wish you good health,Dr. Behar. </s>
