Erika23, I’m over 70, I have Atrial fibrillation and the breathlessness I have on hills is attributed to that. I have dry skin which doesn’t itch if I keep it moisturised. Given the number of older women here, who have had CKD for years, with no symptoms or deterioration, I’d try not to over worry about your mum. I think you said she has other health problems, as do most people in their mid 80s. I hope the GP van reassure you.
Redhead, have you been referred to a rheumatologist? GP’s are, in my experience, often poorly trained and unaware of the excellent treatments available
