Worth having a Synacthen Test?

[Gemma90]

Although my hormones are 'normal' according to the endocrinologist I recently saw, he thought it might be worth me having a Short Synacthen test to be sure before discharging me based on having nothing to do/no ideas to help me.

This test sounds horrible and I don't really want to do it, esp as I can't stand blood tests or needles, but I would def be up for doing it if it could throw something up that could be causing my dry eye/mgd problems....

Can something endo/adrenal gland related cause dry eye/mgd problems?
