Has a skin scraping ever been done on her? That would be important. Have you ever looked into Pyoderma? That can sort of blister, scale/flake, fester a bit. Or, she could be have a severe allergic reaction to something - perhaps something her paws are coming into contact w/ outside?
I don't know...it just sounds too severe to not be able to find out what it is...
