Premenopausal symptoms?

Lately, I've been feeling the cold more than usual, and it quickly gets hot.

A few days ago, I suddenly felt a hot sensation on my face, and then it suddenly went away and became okay.

And sometimes I even break out in cold sweat. My face especially does that..

I'm already worried about whether menopause will come soon... I'm also worried about frozen shoulder...

Is there a way to prevent it in advance? Do I also need to visit a hospital for menopausal symptoms?

Should I go to the obstetrics and gynecology department then?
