Hi Ann, just a thought about you changing Mil's dresssing. I know from what you've said before about how often she injures herself so this may be useful, if you don't know about it already. Have you ever used medicinal Manuka honey on a dressing? It's a wonderful antiseptic, and wounds heal really fast if you use it. My OH had a gangrenous big toe a few years ago. To cut a long story short, he was hospitalised for 2 weeks for intravenous antibiotics and then sent home. He saw a NHS podiatrist for several weeks and she gave us iodine dressings (I was changing them for him). Although the gangrene had then gone, the wound it left on his toe was taking ages to heal. Then at one appointment there was a different podiatrist and she used a Manuka honey dressing. The improvement was amazing, almost miraculous! Within 2 days the wound started healing, and within a fortnight it was completely healed over. I always keep some in now to use on cuts and abrasions. You might find it useful for Mil. You can buy it at most chemists and also, I think, at Health food shops. Also online.
