bacterial infection
"I've seen patient reviews where many terrible side effects of this drug were listed. After that, I was afraid to start taking Cephalexin! But my pharmacist said Keflex has been on the market for decades & most people have no problem with it.  I'm happy to report that I am one of those people! The only side effect I am having is a lot of smelly gas & very smelly bowel movements.(a result of the bad bacteria dying off, perhaps?). But that's a small price to pay to get rid of the infection in my ankle, so I'm quite satisfied.  Word to the wise: I think that most of the patient reviews we see online are from unsatisfied patients. Most people that have no problem with a medicine probably don't take the time to post, so keep that in mind."
