My son (11), daugher (7), both has trunk light rash and sores in their mouth (but, they both do get canar sores). My daughter (7) has had and upset stomach for 5 days. Both my daughter (7), (4), had very badly hurting feet to the point of crying and not being able to walk with red blochy areas that are warm to touch and swollen, but not blisters. Both have one foot worse than the other. My four year old threw up for 14 hours straight 4 days ago. Girls seem a little more tired than usual. What the heck is going on????? Help!!! Thank you!
