Any "Rx or Drug" is toxic to one's entire system including our brains. Popping a pill is an easy solution, but carries with it severe if not deadly side effects. The reality is that Nothing takes all pain away. It is a constant, and with FM flairs, it is a extremely painful ordeal.
All the research I have done points to a combination of 1 or 2 Rx's (the effortless part). I found that keeping prescribed medications kept me from many severe side effects.
As for me, Yoga (can be chair Yoga), Meditation, Heat, Heat, and more Heat (IFR Sauna at my gym)
Daily Stretching, Pool exercises, Walking, Tai Chi, Qi Gong (increases stretching and increases energy) all in moderation so as to not trigger a flair, all are important.
Messages, good nutrition (gluten free because gluten creates fibrin which creates the continuance of pain).
Also, dedicated efforts at Sleep to heal mind, body and soul is important.
I do use 10%menthol, 4-5% Lidocaine cream and Magnesium lotion in combination and it does help with pain after my morning and evening hot shower.
A lot of credit goes to taking our mind off our pain and busying oneself with housework, gardening, art, music, developing spiritual/meditative and positive mindset,and helping others.
Pain control is not easy. We each have to invest time and effort to self-care because we each have other things to do and we Can Overcome this obstacle called chronic pain.
I am wishing all of us FM humans a peaceful, happy and calm inner life as we travel through whatever we have to travel through. Many blessings.
