my granddaughter is 2 years old has a rash like a heat rash ,but is not herself ,her appetite is poor, she is very grizzly ,normally a very happy child, she gets very hot and sweaty when sleeping as though she has been in a bath. When she wakes she is in a very odd tizzy and inconsolable, just crying all the time, recently my daughter has had a rat problem, in her garden shed, little one plays in the garden. could this rash be related to weil,s syndrome, or am I being to cautious.
