Have just had my first Endocrinologist appointment regarding high calcium levels found in my blood. She's referred me on for ultrasounds on parathyroids and kidneys, to see a surgeon, and to see a specialist for more tests regarding bone thinning (not that I've ever been told that I have). I was so taken aback by the prognosis - that I probably need surgery to remove a parathyroid - that when she asked had I any questions, I said NO. I can't believe I forgot to ask her IF this also was causing my chronic fatigue too. I had an subarachnoid haemorrhage several years ago so obviously I suffer fatigue from this. Would be pleased to hear from anyone who has undergone this and did you suffer cfs beforehand? How is it you feel now? I have a brain injury so cfs is common, but it would be great to hear if some degree of it could be relieved by surgery.
