I have random, violent spasms in my right hand that have caused me quite a few burns and other scary accidents. After recently going off Pristiq, there seems to be a decrease, but it's a little early to be certain.

Baths are sooo much easier for me. If the sound and vibration of filling the tub exacerbate her pain, perhaps you could prepare it for her? I use a large aluminum bowl in the bath to wash my hair.

I find taking a bath also helps to regulate my body temperature when I get an episode of the chills or night sweats.
