constipation, chronic
"This created very messy and uncomfortable stools, but any relief was better than none at all. But I am a college student who works out regularly and eats pretty decently. I had 2 allergic reactions and the second one was a lot worse. My lips and tongue were numb, my chest was tight, and I had to run across campus to find Benadryl. It wasn't fun. NEVER ignore signs of a possible reaction."
