Excessive Mucous passing during BM

[Mbailey1017]

On August 4 @730 pm I had picked up a grilled chicken sandwich from a fast food restaurant I ate a few bites and realized it didn't taste right so I threw it out. About 1am that night/morning I woke up with awful diarrhea, no blood was present in the stool. I began to have chills and run a fever and constantly running back to the bathroom every 10 mins or so. I figured it was bad chicken I ate. I called out of work the next day and the running to the bathroom slowed down. I only ate blan food like crackers and bread and ginger ale and gaterade nothing else sounded good and I was neausous for several days that I lost about 20 lbs. my symptoms went away for about a week and then they came right back even with eating practically nothing. I went to my family doctor and she collected stool cultures on my for campylobacter, shigella, ecoli and c diff and all cultures came back negative. She check my ESR thinking it was colitis but that was normal along with all other blood labs. This was on August 30th.She prescribed me ciprofloxin during the time the labs were collected and it worked! I could eat again and had normal BMs! Until about two weeks after I finshed the meds And on sept 22 i began having large mucoid BM and now it's straight mucous have having the urge to go all the time like I did before. I asked my dr to refill my cipro because it seemed to help but she refused and wants me to go to a gi dr. That doesn't fix my problem until she sets up an apointment. But what can this be ? I was sure it was bacteria food born. Please help me any ideas on how to stop this would help !
