Mucus in stool, and nose?

I've had diarrhea-like stools, but it was orangish in color, and I believe it had mucus..

I've done it 4-5 times, but very little at a time. Last time this happened, it was maybe a week or two ago.

I've had a cough 2 weeks ago, then it eventually disapeared..This week, there has been a lot more mucus in my nose, and I usually swallow it, or suck it back in my nose..I also wake up in the morning with a mucus-like taste in my mouth..

Considering the mucus in my nose, the cough, sinus headaches..etc I'm guessing it's not irritable bowel syndrome, or anything to do with my digestive tract..What can I do to help it??

Also, don't tell me to go the the doctor..If it persists, I will, but last time, it was for a day and went away fast. Plus, I've already went to the doctor, and all they said is that it doesn't seem to be viral..(This was before I had the mucus in stools)
