Natalie's sister was not feeling well.  I took her to the doctor and they tested and treated her for strep throat.  As a preventive measure, they gave her sister a prescription as well.  Two or three days past and Natalie began to break out in this itchy rash.  It covered her from head to toe.  Little did we know, Natalie had mononucleosis!  The antibiotic reacted to the mono and created the rash!  I just thought this was crazy.  We had no idea Natalie was even sick!  She had no symptoms until she started the antibiotic!  Has anyone else seen this?
