Hii, Welcome To HCM & Thanks For Asking Your Query Here your observation of having a lump there may be related to variety of medical conditions including cervical polyps , an fibroid or an vaginal abscess and yes it can be a Late inflammatory reaction caused by urethral sling which u had before 6 months but it needs thorough medical check up and investigations to spot a confirm diagnosis as You are post menopausal and in this stage even mild vaginal bleeding is never normal so i will strongly advise you to contact your Gynecologist, he will perform a physical examination to check for any lumps within the vagina and he may want to perform a biopsy on any masses found in the vagina to rule out other sources of the problem I hope it help Thanks & Get well Soon
