I bet the majority of patients has not been to an endocrinologist. If they did, they would probably be sent right back because Sjogren's is not their speciality...
For me, problems began in my late 20'ies/early 30'ies when my periods suddenly dried up to barely a few drops monthly. My life changed dramatically. Beautiful sensations went dead (music, scents, being touched, libido, etc).
My gynaecologist congratulated me on having such minimum nuisance because most patients complained of the opposite. My sky high estrogen level he compared to being on BCP and thus surpressing blood flow. If only he'd tried to lower it! Fifteen years later 5 large uterine fibroids due to endometriosis had to be surgically removed...
When he finally measured my extremely low testosterone levels, he wouldn't prescribe anything for it...
Desperately I turned to naturopaths and discovered by trial and error which hormones can alleviate symptoms. My sensations were (partially) raised from the dead

Rheumatology is viable route, which I deterred from after being offered drugs with dangerous side effects. But for some people it works. Maybe even better if combined with hormone replacement therapy? Might be worth a try...
