Thank you very much for the useful information Nikki.
Yes, fibromyalgia should not give you discoloration of the legs/ankle but we are not sure whether this discoloration is part of the ongoing pain/disease or not.
Fibromyalgia is a diagnosis of exclusion which means all other possible causes need to be ruled out before attributing this pain to fibro.
I can see that your doctor has rightly ordered most of the tests required, but i was wondering if this is due to vitamin D deficiency.
Its very common, especially amongst females, and a simple blood test can diagnose this problem. If found to be low, appropriate replacement with vitamin D should solve the problem.
For the pain in legs, a doppler ultrasound will help identify any circulation issue to the legs (due to clot/cholesterol build up in the arteries), which typically give color changes/pain whenever you walk or exercise.
So this is another possibility that needs to be ruled out.
Having said that, if these tests also turn out to be normal, then this could be fibromyalgia and in that case you should begin the treatment for fibro, which must show improvement in your symptoms to great extent with in 4 weeks.
Right now, keep yourself adequately hydrated.
Rest and little exercise might help (if tolerable).
And get back to your doctor discussing the details i have mentioned to get further management plan chalked out.
I would have been worried too if I were at your place, but let me reassure you that this does not sound serious at all. It is a treatable condition and carries a good prognosis with appropriate management.
It was a pleasure assisting you and thank you very much for visiting us.
