my 22 year old daughter broke out in weeping lesions from her scalp to her face and ears and down her neck to her chest .She is horribly sick and vomitting grey water(it look like that) and has lost 70 lbs in four months without changing anything. I took her to the er 3 days ago and they booked her in next week to see an internal med dr. but her vomit was not this colour and her body is very itchy but painful. The er dr . said it was not the shingles that we possibly thought and she has never had chicken pox . do i need to take her back to the er before her appt. she has been sleepy and fragile.
