I have studied your case. Fibromyalgia
is a diagnosis by exclusion and mainly diagnosed by clinical examination.
For lupus you can do blood investigation like ANA,ds DNA, if those are positive then medication can be given.
Fibromyalgia can not be totally cured, you can only minimise symptoms by taking various medications. As you are resistant to amitryptiline and duloxetin I will advise you that you can start milnacipran
or Lyrica (pregabalin) consulting your treating doctor.
Exercises and stretches plays important role in maintaining symptoms of fibromyalgiaPhysiotherapy
like ultrasound and tens will help, along with knee exercises.
A holistic approach is required, which includes exercises, meditation
,SKY[ sudarshan kriya yoga] and acupuncture
along with healthy diet and herbs.
