I am in so much pain at night on a very low part of my left back and it runs down my leg , creates numbness in my foot , and I also get terrible headaches when I m laying down that are worse when I m laying down. Years ago if I had a headache it would improve by laying down. I have also had breast cancer, two mastectomies just six years ago. I m now also bleeding from my rectum. Sorry to give you so many issues, but I sure value your help, Thankyou dearly. From Dana Gammell
