talk to your doctor about estrogen testing...Im assuming you still have ovaries,,,they often dont function "right' when uterus is removed..if your low on estrogen and I bet you are the cure is simple...I choose the patch its easy and no bad side effects...its a simple blood test to determine if you need hormones.
I agree with cherie, i had the same problem, go speak to GP and he will prescribe hormone treatment to help there is also a pill you can insert inside called vagifem which help to plump up the skin inside again, to get things back to normal.
