Hi, a few days ago I woke up and was vomiting a lot and could not keep anything down, including water. The next day I came up with a rash which covers all up the inside of my arms, across my chest and stomach, down the back of my legs and on my feet as well. It is the 3rd day now and I am still feeing ill, although the vomiting has stopped, my stomach still does not feel settled either.
