I sure hope your wife has a great sense of humor!!
With my MS, I don't need PMS to be bitchy.... I do fine with just with MS alone.
Really, I sound just like your wife, only I am still mobile. That why I chose not to wait.
The feet issue with me started with closed in shoes. I started wearing slide on shoes or "mules". Then it went to socks. I could not stand for socks to touch the top of my feet or the front of my legs so I went to the no show socks, which still drive me crazy since they touch the top of my feet. So my next step was flip flops, which I wear almost 12 months out of the year so nothing touched the tops of my feet but the cloth straps (no plastic, can't stand the plastic flip flips) As you can see I am very picky. I am hoping that it does not get worse!
I too am ready and willing to talk with her all you need to do is PM me and I will send you my email address.
Best of luck to you both and tell her I would do the stent again if I need to.
