@dreichelderfer Welcome to Mayo Clinic Connect! The best way you can help your wife is to educate yourself so that you can really understand what is going on with her. I don’t know a great deal about fibromyalgia but there is a whole support group for fibromyalgia patients here: You can ask the folks in that group how best to educate yourself and how to manage her pain.

It may be a tough road for both of you, but together, nothing is impossible!
