I am a postmenopausal woman (65 y). I stopped estrogen
treatment in January 2013 but have sometimes used local estrogen and lactic acid. I have had problems with my urinary opening, vaginal atrium and vagina. My distal urethra has been swollen, sore and smarting. On May 7, 2013, I found a "sand" grain betveen my labia. It vas brownish, with innumeral vacuoles and some regular structures, not exactly like microvilli.
