I believe one of the people giving testimonials on the DVD suffered from fibromyalgia. I'm not familiar with it, but SFQ has several testimonials about it. In fact, I think LSC web pages has some SFQ testimonials now. Take a look I believe fibromyalgia is one of them.
As for pushing through the hieghtened experience of the symptoms, I would suggest a change of attitude. Try and make it one of staying with it. Changing it from an experience of struggle, force and determination, into one of release, surrender and trust.
This next isn't from the SFQ material, but it helps me at times. All sensations (feelings) are packets of energy and are gift to us. In the Feeling exercise (the way I first was introduced to it) you feel the feelings without judgement or labels. You're just with the feeling, with the energy. If you understand it is a gift from the universe it is easier to love the energy, and be grateful for it.
From the SFQ side, you trust that the energy is directed by the universe (this is where usually say the love of the universe) for you best, and acknowledge that you may not and possibly can't consciously understand how or what it is creating. Confidently trust in the universe and the experience becomes a lovely gift.
All pretty words aside, you are your own best guide. Listen and follow.
You are perfection.
