Hello, I suddenly got a sharp pain at my left back (above the waist line) for an hour last night. I was sweating. The pain was continuous not the rhythm one. I took 2 Advil - the symptom (pain) still was continue so I took another 2 Tylenol pills and be able to sleep after 45 minutes. The pain is gone when I wake up this morning. I don t feel any pain now. I think about what I did the previous day: cleaning the fish pond (2 days ago), was continued to work on the fish pond (light work - yesterday), reaching to open the passenger car door lock few time during the week, ate yesterday breakfast the food had a lot of cooking oil, ate fried meat. The question is: Should I go to see my doctor? What should I tell him if I go to see my doctor? Will he be able to find out anything? Thanks for your times and answer my concern. Bower Nguyen
