Doctor, I'm having pain in my abdomen. It started in the left lower abdomen. Nothing sharp, and not constant. Went and saw a doctor, he advised an ultrasound. So took an ultrasound of the whole abdomen. All he was able to find was a 5.3mm stone (he said it may not be one, as these minor things can be a glitch in the scan). Still provided medication for the same. Now the pain is resurfaced. Its now more to the center left of the abdomen. Pain is bit more constant than before. If i eat full, then it hurts a bit more. When ever i take a huge breathe in, it aches a bit too. what could be the reason. Im not facing any other problem.
