I can honestly say that I did not know what Hand, Foot & Mouth disease was until this week. It has to be among one of the most painful sicknesses a child can get. Casey started with symtoms on Friday afternoon - fever, not feeling well - and by Sunday night she had sores all over in her mouth, tongue & throat. Her mouth is so swollen, it looks like she got smacked in the face. And it hurts. They say this lasts 7-10 days and this is day 5 of pain and suffering.
