Can anyone help please? My friends dad is elderly & in hospital at the mo. He has various illnesses including diabetes, COPD & takes warfarin daily. He was admitted because of cellulitis in his leg but it just isn't getting any better & no one in the hospital is giving her answers or have said they know what's wrong with it. Also his sodium levels have increased so he is now on restricted fluids. My friend is panicking about him so hoping someone here might have a suggestion as to what's wrong with his leg as it doesn't just look like cellulitis any more. Thanks in advance.
