Hi Our daughter got very sick on Monday after a visit to the children's ER at Memorial Hospital in Hollywood, her 2 year old bumped his forehead and she took him in for a checkup. symptoms were severe faucet like vomiting, horrible cramping and low grade fever and severe diarrhea all at the same time, it lasted for about 6 hours and any attempt to hydrated with sips of ice, gatorade cause the vomiting to returned. Her two year old got similar symptoms and was taken back to the ER, but he did not showed symptoms of a contusion but it was questionable since there was a previous incident. after observation he was sent home and we keep him at grandma's and gramps overnight. on Friday night grandpa developed same symptoms and was violently ill and of course grandma followed. last night our daughter's husband came sick from work (Hollywood Airport) and just an over ago our grandson started silently throwing up just like before. Ay idea of what we're dealing with? needless to said our joints hurt, our head and we are very weak but recuperating trying to keep hydrated
