I have foot ulcers, now 2 years old, and stasis eczema, the ulcers are caused by scleroderma, the eczema by my immobility. Scleroderma causes my skin to break down and unfortunately this is also happening on the underside of both wrists. Doctors think that an ulcer here is how I ended up with a terrible case of cellulitis necessitating a 10 day stay in hospital for IV antibiotics. Let me tell you my hand, had to be the right one as I am right handed, was so painful I was actually disappointed when the doctor said no to surgery in case the incision didn't heal. I asked they cut if off instead.
Anyways the constant bandages on my feet mean I by shoes 2 sizes to big and as I use a wheelchair I don't walk much in the footwear so don't suffer any side effects from wearing such big footwear, assuming I would suffer side effects from it! I was going to suggest that you consider larger footwear and depending on how much walking you do, slippers/slipper boots. I have been out many times in both, you gotta do whatcha gotta do!
My feet are covered in tight skin and have lost much of their padding and as I can't bend my ankles shoes with any sort of heel are out of the question so even pre ulcers I had to be selective with footwear. What I would not recommend are catalogues advertising "comfortable" footwear, designed especially to be a treat for your feet. Not only ugly but actually uncomfortable and overpriced, well I did order about 6 boxes of them. I found better in a high street shoe shop that had their own comfort range. I bought a pair of dark pink, patent sandals with velcro adjustable straps, not just at the ankle but also across the toes, for maximum comfort. They might be 2 sizes to big but they're pretty, pink and comfortable!
Tomorrow is supposed to be sunny and warm, warm and sunny tomorrow, tomorrow, sunny, warm...how many time do'ya think I have to write it to make it happen??
