I am a 16 year old male, and for the past two weeks, on and off, I have been experiencing some form of constipation, excessive gas (mostly at night or in the morning), and recently, bloating. My stools will sometimes be round "pellets" for some reason, and it looks like theres mucus in it. (Maybe it's because I have been having sinus drainage in my throat in the last week?) Also, sometimes I will have mild diarrhea, followed by the constipation. However, I am still passing about 3 stools per day, which makes me think it is not constipation, but i cant find a name for it yet. Sometimes I will have a small amount of diarrhea in the morning, then I will pass the round "pellet stools". Sometimes I get stomach cramps while doing so. Does anyone have any ideas? I am taking Prevacid and allegra-d if that matters.
