Fecal Impaction?

Question

I'm having pain in my lower left stomach and back. It really flared up five days post-op from gallbladder removal surgery (laparoscopic). Also had my kidneys looked at. Left kidney is only functioning at 30% but this should not be the cause of my pain. Now I'm having gas and bloating. Been in the ER 3 times in five days with this pain. They prescribe pain mess and send me home. I finally figured out the pain mess could be causing constipation. I cannot seem to pass a good stool! It's mostly liquid with some strange looking smaller feathery poops (sorry so graphic!). I have done Fleet enemas and the liquid comes out along with the gas. How emergent is this? Please help! I feel bloat and pain and am obviously stumping the ER's here! Thank you!
