By a specialist do you mean an endocrinologist or someone else? Because I did see an endocrinologist and all he did was check me for addisons.
Also I forgot to mention that sometimes my calcium is high and sometimes it isn't. I've had it checked many times over the past 6 months. It seems to be 50/50
Calcium fluctuations is another sign of a parathyroid growth.
You need the advice of a dedicated parathyroid surgeon. Dr James Norman and his surgeons carry out 3.700 parathyroid operations/annum.
There is a form to click onto on his website where you can get questions answered and advice from a surgeon on whether you may have hyperthyroidism. They will need your lab readings particularly all Calcium, parathyroid hormone(PTH)and Vitamin D levels.
