diverticulitis
"This drug should be banned from human use.  It permanently disabled me by attacking my corpus callosum (middle brain) - the first time.  I had t to resign from my federal job because I could no longer walk, talk, or write.  After treatment at an acute rehab, I got C-diff and was prescribed more flagyl.  I began to fall on my face.  After several brush burns and other related issues I was in and out of the ER.  Four years later, I am left with slurred speech, vision and heart issues.  To date no one has taken responsibility for this drug."
