Hi, I Have Lower Back Pain. It Becomes Sharp When

Hi, I have lower back pain. It becomes sharp when I move suddenly. A month ago I was told I had a herniated disk because of severe shoulder pain and finger numbness. It has passed but now it is my back along with leg numbness. Headaches , frequent urination. I get out of breath pretty easy and am tired often. Pain in my hips also as well as brown stringy blood between periods. I'm scared to death that I may have cancer. I am uninsured but will go to the Dr next month when I'm paid commissions. Just want to know that there is a possibility that cancer isn't causing everything.
