Good Afternoon My Name Is Andrew Johnson .I Have A

Good Afternoon
My name is Andrew Johnson .I have a spinal cord injury and illeostomy ever since my injury in 2009.I had a lacerated liver and a almost failed pancreas due the gunshot wound which went right through but i still have a few fragments in me.i had surgery to move my colostomy bag more up on the right side of my stomach this past april. I recoverd well but ive been feeling this tiring slight pain in my upper right quadrant, it comes here and there mostly when im walking up stairs and other active movements. Lately ive been experiencing gas pains due to eating nothing but dairy products,eggs cheese,cereal. The gas feels like its still lingering around but i can tolerate it now. But the upper right quadrant pain is back a bit worse then before it only acts up when i get up or make something to eat and ill have slight pain in my back and my left side. I have no tempature or no signs of infection. Could it be the gas thats causing me too wonder im curious. Thanks for your time
