I have nausea 24/7 but depending on the day or what time it is, it's intensity changes from Ok to I feel like i'm going to faint. Recently I have had a increase on the amount of mucus on my stools (sorry for graphics.) I have got Polysistic Kidneys but I am a teenager so that hasn't really affected me yet. I have severe (health/general) anxiety and am quite isolated. I went to a doctor about 4 months ago and she told me that I had bad nasal congestion due to a blockage within my nose. ( I do not have allergies) and within the last week I have felt blocked up again .Could my anxiety or my nasal congestion be causing my nausea and mucus in my stool?
