Odd Sensations, Reflexology?

The burning at the base of my spine is back.

I took a cleansing bath in salt and hydrogen peroxide as directed
and now I have this pin pricking tingling burning at the base of my spine.

I would think it if it were a skin reaction it would be happening all over.
Why there?

Also, since last night, I am ACUTELY AWARE of a crease on the inside bottom of my
right big toe. (the side towards second toe)

It's not burning, or itchy, I can just feel the crease.
(i've had athletes foot before, so I know what that is like and this is not it.)

It's just an AWARENESS that I have this crease on the bottom of my toe.
It feels like there is a piece of tissue paper stuck to it or something.
just a tiny little bit of difference from "normal" enough to make you notice.

Anyone with any insights is welcome to share!

blessings to you dear reader
