<s>[INST] Hi. I ve had a constant pain/ache in the left side of my abdomen since last Monday. It was very sudden inset and I was sweating and shaking and actually thought I was having a heart attack! It has eased a little. I have also been getting pain in my left shoulder and collar bone. My gp initially thought it was an inflamed stomach and then a few days later kidney stones. I have since also have a slight cough and harsh voice. Am getting to the end of my tether now and have has enough of the pain. I can t lie flat, take deep breathes without the pain and also sneezing etc hurts! [/INST] Hi. Thanks for your query and an elucidated history. The cause of sudden abdominal pains, shaking and sweating can be due to the following reasons:Since your pain is increasing on lying down, deep breathing and also sneezing, we have to concentrate on the lower lung, pleura and upper abdomen-The causes can be a pleurisy, lower lung infection, infection just bellow the domes of diaphragm. These mimic heart attack and hence it is very important to rule out the heart problem. Get EKG, Eco -cardiograph, stress test done if possible under the care of the Cardiologist. Get a Ct scan of the chest and upper abdomen to see for the lungs or colon problems. Severe colitis, diverticulitis to cause the similar problem of sudden pain, sweating and shaking. The additional blood, urine and stool tests and Colonoscopy if the EKG is normal can tell us better diagnosis and a plan for further treatment. </s>
