Hello,
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 fibromyalgia
Physiotherapy 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.
Hope this answers your query. If you have additional questions or follow up queries then please do not hesitate in writing to us. I will be happy to answer your queries.
Wishing you good health.
Take care
