my daughter is 18 and in the past week or so has been feeling unwell.She is always tired,looks very pale,loss of apetite and feeling very dizzy when moving. I thought she may be aneamic but unlike most, she appears to be feeling hot not cold - this is unusal for her as she was always such a chilly thing. she is also feeling sick and being sick. She is not pregnant. Any ideas please? She is booked for blood tests next week.
