my daughter who is 8 swallowed a 2 pence coin, she went to hospital but at the hospital she swallowed it, roughly 2 weeks she deveploed a rash, 4 visits to the doctor after being told it was eczema, no creams got rid of the rash then she was put on steroids for 2 weeks and again the rash did not disappear, on the fourth visit to the doctors they diagnosed her as having scabies and is currently bein treated, now with swallowing the con can this be the cause for her rash (scabies) ?
