My friend, who also has fibro, swears by getting regular massages. She goes to a school of massage - so it's fairly inexpensive. My doctor said he'd prescribe me to have them, but I'm not a fan of massages by strangers... Then again, you could put hubby to work.
Why don't you take a look at the arthritis.org website - they have a ton of brochures - don't recall if they have anything about spouses and fibro. I'm sure there is a similar separate fibro foundation too, but they won't have the resources that the Arthritis Foundation's site.
I'm sorry you're struggling both physically and emotionally. Please look for support - it's important to your care.
