Pain in the upper left quadrant, back and left shoulder most likely originates in the chest or abdomen. The most common causes of pain in the back if occurring after meals are from gallbladder disease, heartburn or gastro esophageal reflux disease. These conditions cause pain, burning and discomfort in the chest that can radiate to the back and shoulder blades. Fever is the body’s defense mechanism against any infection in the body. Headaches and insomnia could be due to stress, anxiety or depression. Get yourself evaluated by a physician. A complete clinical examination and investigations like CBC, ultrasound abdomen may help. Keep us updated.
