my mum's feet

[Pompal 09.]

My mum has developed the most dreadful dry skin all over the sole of her feet. I mean so dry that it is cracking as she walks. It is around the heels like lots of us (in fact that's where it started) but now it is all over. It is deeply cracked and bleeding. She has been to the Gp a few times and he has given her creams of various types. He has since given her a chest xray - she is getting the results next week as she is a chronic asthmatic - well it has recenlty cleared up for the first time in almost 40 years - and has asked her about her digestion. I just wondered if anybody out there had any words of wisdom. her feet are so bad and dry and cracked that I haven't touched them. Thanks.
