I just went for my annual checkup and told my doctor that I was having the same problem. I had a hysterectomy a year ago, and he thought that it may be small tears, due to the fact that there was not enough lubrication. Although I thought there was. He gave me a prescription for Vagifem, which is a low dose estrogen that is put dirctly into the vagina, and told me to use it a couple times a week for a month, and see if it helps. I don't know if it does yet, my husband is out of town. Could that possibly be your problem?
