hi, it seems you have got frustrated after being into this fibromyalgia for a long time. I have seen many patients with fibromyalgia and all have improved. all you need to focus is on doing regular exercise under supervision. second thing to look forward is the yogic breathing. the third step comes here is the meditation. now let me explain you in little detail here. the fibromyalgia is a condition which arises due to the inflammation in the muscle fibres. as the name states. fibro-myal-gia means the fibre muscle pain. now you have RA as well. for RA the importance is to keep the muscles and joints active as it should never trouble the Respiratory system. so for that a breathing exercise is advised. now why I talk about the guided exercises here is because some therapist who can understand you fatigue levels and help you modify all the exrrcises. now working out in this situation looks somewhat an odd . but making an understanding to the body how to cope up with all the possible activities it will always take u to some possible good direction. Now how far I have successfully treated. well I have seen all chronic fibromyalgia and RA cases. but timely modifying and keenly observing the patients progress I grade the exercise. I hope I have helped somewhat to your query. if anything further you want to discuss I will surely stand up. I wish you a blessed recovery.
