I'm 28 had 3 kids already and a lot of sex. I don't know how to explain the pain other than knotting from my lower stomach to my lower back and rectum almost as if you had gas cramps. I have been feeling this after every encounter no matter how gentle. The pain slowly eases off after 30-45 minutes. It hurts so bad I have to stay curled up and can't walk without wanted to cry. Please can someone help I have only been feeling this past 2-3 yrs. Youngest child is 5.
