20 yr old female. my lower abdomen is swollen, i have had blood in my feces recently (only on the outside of it). i poop everyday if not more than once. i often get diarrhea but i havent had it in a week or so. i also have had a cough that wakes me from a deep sleep and lasts about 20 minutes. i cough sporatically throughout the day (worse in the morning and night) i can't tell if my neck glands are swollen they might be a little bit but not much. the cough has lasted me three weeks now. any idea as to what any of this means?
