I had the same thing and was diagnosed with mucous colitis. I was told to lessen the stress in the life and put particular diet. I do not remember the diet now and because it was so long ago, the treatment may have changed. However, I was relieved to know it wouldn't kill or disable me.
Every one has mucus in their stool. But, when we eat something that doesn't agree with us or if we have the flu there is more. That would be a blessing. Best to you!!
probably just irritable colon. Try not to worry.
