I am having several symptoms of perimenopause, from the short, intense painful periods, night sweats (for a week to 10 days prior to my period), radical mood swings, and bouts with anxiety, etc. The worst sypmptom lately is some vaginal irritation, but I can't find what is typical and what is something to be concerned about. What are the types of vaginal irritation that are typical with perimenopause? Lumps? Bumps? Blisters? Dry patches? All I can seem to find online are general references to 'vaginal irritation'. Could you please define "vaginal irritation' for me?
