Hi , I have been on Dexamethasone for almost three weeks now to help with bone cancer pain.. I take 4mg twice a day (just starting to 1 1/2 today...weaning off) . So now I am up all night, bloated, shakey and my Dr. said my thyroid test was low and wants me to have another sort of blood test. Is it the steroid that is causing this? Oh and moon face and swollen side on left of neck. What do you think?
