It is now 6 years since my surgery/chemo/rads, and during this time I blamed chemo for quite a few after-effects - loss of energy, loss of concentration, aching bones, sleep problems, worsening memory. My GP sent me to an Endocrinologist and scans showed an adenoma (small tumour) on a parathyroid gland behind the thyroid. After having surgery and 2 glands removed, all the above have gone!! Literally overnight! No more aches, pains or fuzzies - I feel as though a veil has been lifted! I will bless the day I met my Endocrinologist. Who'd have thought?
