sinusitis
"I was given this medication for a sinus infection and was on it for 10 days at which time I was admitted to the hospital for a severe reaction.  Hospital staff, ENT doctor, and nurses had never seen anything like it.  I have a major burn rash ALL over my body that included very large "clear liquid" pockets.  It has been two weeks and I still have the rash, but it has started fading."
