I am experiencing left side abdominal pain and the middle of the stomach for the past 2 days. This morning i am now experiencing pain in the back on the left side and still pain in the left side of the abdomen.  I have had fever, headaches, dizziness and a general feeling of nausea associated wit the pain.
Welcome to Chat Doctor .1. Let me narrow down the possibilities. First thing with fever and nausea i would think of acute gastroenteritis.  2. Renal calculus, diverticulosis - in a bit elderly age (I cant see your age), adnexal lesions may also cause the above symptoms (if female) 3. Get an Ultrasound abdomen done to rule out the most of the causes. Anything to ask ? Do not hesitate. Thank you.
