Leaky rectum and diharea while running

I really need help!!
For the last few months I have been having rectal leakage and trouble controlling my bowels. I am a 38 yr old mom to a 5,3,and 1yr old. Ive been a runner all my life and lately I am having issues. One day I woke to a bloated stomach and cramping, I got up to get ready and clear fishy smelling muscus was leaking uncontrollable out of my rear. It lasted a day or 2 (with a superbsorbant pads) I went to the Dr where they tested stool samples (all neg.) Then an internal ultrasound which showed my intestenes filled with fluid. They were stumped and said protitis and wanted me try steroids and Antibiotics , which I said no to. A few days later i went for a run and literally 15 min. Into it i needed to go to the bathroom. I barely made it to the rstroom. Lately I can no longer go outside to run since there aren't any public ones. Every day I end up with feces on my pantries,they wanted to treat me with Antibiotics and steroids. I refushed and had a Colonoscopy. Again nothing was found. So do I sick it up and wear mega pads or do I try something different Tweet
