hi, my mother been having a lot of discomfort in her left lower abdomin for the last 4 months. Its mostly a sharp pain during the day, but at night it seems worse. It's very painfull. She can feel it as an internal swelling on her lower left tummy side and a black spot that looks like pressurized internal blood appears on her left lower tummy. The internal sweeling is an inch left from her belly button all the way across and around her left side, down to her hip(sometimes her lower back too). It kind of feels like there something in there.she would feel this strange squirting feeling inside,  she have been taking a lot of drugs from her doctor the last 2 months but the drugs did nothing and she still have the pain and it seems it gets worst. she have stopped taking the drugs and the pain is only continued. she been to the doctor 4 times , and he tested for kidney stones, and looked for lumps.. i have done an anul endoskopy he found nothing and told her to come back after a week to see how she was. she went back, again he found nothing and said it could be stress related. he gave me some pain killers which helped while they lasted.... and toldhere to come back again in a few weeks if it doesnt go away. she dont know what to do, sometimes she is kept awake all night because of it, she guessing she going to have to see the doctor again, but first id like some more opinions on this sorry about the lenght of this
