I was diagnosed with this a few years ago... Never offered any treatment. Mine comes anf goes, has done since my 20s. It us horrific, but then I have periods where I have no problem with it at all.
However, now at 45 (and on this forum with hormonal issues), I swear mine is hormonally linked.
Are you on any hormonal treatment??? May be worth considering when it started /if it goes and returns... Look for links.
