Hello, A few weeks ago I noticed after sex with my husband my vagina muscles just fell like they were wore out or something. This seemed unusual to me and it has been a few weeks and I don't know if this is normal or has to do with my illness. I have MS and I am 31yrs old and I am not sure what to do about it. It doesn't hurt or anything but I am not sure.
You should see a doctor. You may have a vaginal prolapse. According to WebMD, "A vaginal prolapse is a condition in which structures such as the uterus, rectum, bladder, urethra, small bowel, or the vagina itself may begin to prolapse, or fall, out of their normal positions. Without medical treatment or surgery, these structures may eventually prolapse farther and farther into the vagina or even through the vaginal opening if their supports weaken enough."
