My husbands lower legs are totally discolored, almost purple-blackish red. The skin just flakes off in large areas, his toenails after a fungus desiese all just fell off, now new ones are growing. all topical creams so far failed, he is on anibiotics now, makes no difference. hi is 73, his legs look like they are of a dead-man. Terribly embarrassing, uncoffortable, they also swell a lot. His dr. just tries different creams, none work no blodclods foung, but must be some bad infection or....some internal problem. No, I am not a doctor, but I see his problem getting worse day after day.... helop please
