What is the most interesting yet disturbing fact that you know?

A rare medication reaction called Stevens-Johnson Syndrome can cause your skin to blister and eventually peel off similar to a third degree burn victim. It's a horrible drug reaction and has a very high mortality rate.

It can be caused by almost any medication, including ones you have already taken before and had no prior reaction to. The most common medications that cause it are antibiotics and anti-epileptic medications.
