"a tvt tape"

I had a tvt fitted 3 years ago, for the last one and a half years iv been experiencing a dropping sensation, severe pain, and numbness on the right side of my vagina and groin area, if I have intercourse the pain is a hundred times worse and so I now avoid it, which is not doing my marriage any good, I had a vaginal scan done but nothing was found, I am going back to my doctors in a few days, this is really depressing me.
