Yes,
That's the same sweat test they did on me last Dec. You can look it up on line to see what they are like. Fanfaire, Be prepared to have purple hands, knees, feet, etc. Anywhere the skin is dry it will stick more. My hands were purple for days as were my feet and the sides of my body where I couldn't reach to scrub. Underarms were purple. It just has to wear off. And you will see lots of people at Mayo with purple hands and feet (if they are exposed). They are pretty common. I wish I'd know she were going thru this, I'd have had some hints for the eyes. The box is so hot and dry.

Also,
be sure someone sends you to a Gastro. You have problems and if it's Sjogren's and neuropathy, you are likely to have more. This all needs to be documented.

Good luck to your husband. I know the weather is so bad.
