From last almost 15 days i'm experiencing lower abdominal pain on both lower right and left side of abdomen. It's like stretching frm inside, i'm having loose stomach and have no appetite for food. All day I feel exhausted and this takes toll on my daily working routine and office work. I can't concentrate. I'm taking pantocid d two times a day and already taken antibiotics for some days back but of no help. I'm now fed up of this, pls help.
