I don't have the sweating issue as of now and am not comparing my moms problem but thought it may help with direction of what could help. I know my mom who does not have RSD but I am thinking it was from menapause used to sweat under arms where it would leave marks and she found these shields at a langerie store so I wonder if they have similar for other body areas if you find parts sweat more then others. Also what about different materials or weights. I know for me on my legs where my RSD I can only tolerate certain textures and weight to it. I go around feeling all the items in the store to see if it is even a possible.
