<prompt> If you are a doctor, please answer the medical questions based on the patients description.am 27 years old lady , I have been feeling a pain in my left lower abdomen for the last two years , I gone for a check up but everything went well , a few months later the pain come back and I went to another test where I have done an ultra sound scanning but they did get anything . am so worried about my condition because the pain is still there please I need some help  <response>: Hi. Thanks for your query and an elucidated history. If all the tests are normal, means there is the least chance of the problems which could have been detected by the tests you have undergone through. Your pain is:Left lower abdomen - 2 years- ultrasonography is normal- A good clinical examination by a Surgeon with proper physical examination can definitely get the diagnosis. I would think of colitis - this is not picked by any sonography. GO for colonoscopy take a course of an antibiotic, metronidazole and anti-spasmodic for 5 days. If this helps, nothing to worry about. You may consult a Gastroenterologist to have further clinical examination and investigations and prescription based treatment. Stress does increase such pains as also sort of allergy to some foods and beverages. If you have noticed - please stop consuming them.
