My wife practices reflexology and I was a skeptic. She started practicing on my feet (after getting over the sensitivity) and now I schedule appointments with her on a regular basis. She has given a reflexology treatment to me for specific ailments and just to help relax.
To answer your question, I feel better after having a reflexology session and surprisingly, it has helped to take away some problems I have experienced in the past.
She's actually just starting with a new client who suffers from the same symptoms as your mother. If you have any more questions she'd be great to speak to about them. I'll reference her site and another with an article about whether or not reflexology works. Contact her if you like.
