The ONLY thing I could recommend, is adjust the water of your bath, to suit your rsd foot.
Short of that, I don't know....

I've learned that (since I'm whole body), that I must adjust my bathing/shower water, to suit for my body.
Put differently, I may like very warm water. Yet, that rsd part of me can't take it.
I must learn to adjust to luke cool water...

But, I know someone else will speak, since i'm whole body.....
And, I have big problems with closing my pores if I take my "preferred" warm bath/shower. Even when I get out, it seems to take at least an hour or so, for me to get dry. It's like I can't close my pores. To the extent that I'll sit in front of the A/C.
Thank God I live alone!
hah!

Now, I've learned, that I must, be un comfortable in the bath / shower.
No other choice.
In the home, that I built, to suit myself, my bathroom(s) had exhaust fans, auxiliary heat, whirlpool, and... like that.

Now, that Wifey took that, I feel as though I'm camping...
Maybe that's a good thing.

Go camping...

I do whatever it takes, open windows, if it's hot, turn on A/C (not exactly camping), If it's cool, raise the humidity. (by running the hot shower for a bit).

There are many ways, to deal with the "atmosphere" that we live in.
Keep it to the smallest part of your home that live in, until you're comfy.

I also notice, that pain reliever's, (Opioids), will fool your body.
So, take those After the bathing process.

Hope you feel better!
