Hi,
Welcome to ehealthforum,
If the problem of vaginal pain and painful intercourse or insertion has been present before your childbirth, then problem could be attributed to causes other than the hysterectomy and other procedures. You should consider visiting your gynecologist/obstetrician for further evaluation to look for the underlying cause for the vaginal/vulval pain (vulvodynia, vaginal spasm, vaginal endometriosis, scar tissue formation, vault problems etc). The evaluation and examination done would also confirm if there are any problems with the vault (that can be corrected). If he pain is severe and affecting your sexual life and quality of life, you should consider discussing about options of further surgical management involving nerve blocks (you can try with temporary procedures first to see if they give you relief and then make your decisions). The options of the treatment and further management would depend entirely on the examination and investigation findings. Do not delay in visiting your gynecologist/obstetrician or consult a pain management specialist for further evaluation and assistance.
Take care.
