I have had some of that for years 1 wear a light pad every day. It is largely abated now. I don’t know if you are post menopausal but mine was sloughing cells due to vaginal atrophy - since I had total hysterectomy at age 38 and was untreated for 30 years. I finally had it diagnosed by a Uro-GYN and I have been on 10mg vaginal estradiol twice a week since 2016 and that keeps it in check. Just a thought to mention to your doc if you are post menopausal.
