as a 39 year old female i suffer severe lower back pain that started during my 3rd pregnancy 8 years ago. Its is mostly when i get up in the morning or when i sit a certain way. i also have odd periods. It starts and stops for 2 weeks at a time. i also suffer from cramps which used to be mild but are very uncomfortable now. I am not interested in pain meds so i just take advil, which offers no felief. When i told my OB about my probs, he seemed to just blow it off and say i have had four children and its hard on a body....it has really affected my quality of life and now as a healthy 39 year old, there is a problem. Could I have a uterine cyst? Doing a little research online has shown me that my symtoms point to this, what is my next step?
