Exactly 2 weeks ago today I found blood both on the paper and in the bowl after a bowel movement (it was difficult to pass and stung) since then I've had mild constipation and diarrhea. I've also had odd feelings in my stomach area (though I think this may be caused by anxiety, since I have chronic anxiety) then this morning, after holding a movement for about 10 Minutes (roommate was in the shower) there was blood again and the same stinging pain. I'm a 20 year old woman, I've had fissures in the past but nothing like this, I haven't experienced any light headedness or weakness, and there hasn't been any change in the colour/shape of stool. I exercise daily but I don't drink nearly as much as I should. I'm convinced that this is just hemorroids but I'm stuck on thinking it's something worse. Should I be concerned by this or should I wait and see if it continues?
