I don't now what to think

I have been having trouble. It started out with my ears and they were stuffy I had been to several dr. and then they told me I had alergys that was causing this mucus .  It seems to build up and then travles down my digistave track and its in my stool sometimes its sort of painful but diffently irritable.  Could this be more then allergys (allergies) they tested me and I was allergic to mold.  

Thanks
