It never ends sometimes, right? I mean you're trying to take care of your back with the brace and then the sores. I wish I had some suggestions for you, and i hope someone else comes along who does. I just want to send you healing thoughts, although I know that doesn't help much.
You're doing everything you can. Keep searching because maybe you will stumble on someone who's been through it that has a creative idea. I wonder if anyone in any of the medical supply stores (where they sell things like the braces) might have any ideas? Just a thought.
You're so thoughtful to still put a smile on and wish us sunshine even through your pain!
Sending smiles back to you!
