Why Does Vaginal Area Always Feel Uncomfortable?

I have been dealing with an issue for years off and on. I sit at work or home and my vaginal area just feels uncomfortable, not painful. I have tried different creams. I have tried different pillows to sit on but nothing seems to help. I had a hysterectomy in 1987 and I also had a sling put in so I would not have issues with wetting. I m at a lose. What can you suggest. Yes, I have been to several doctors and they really don t have any answers. Please help.
