question: I have had a knot in my back for a year now. Ive had a lot of severe back and hip pain for over a year and have been to numerous doctors and havdle had numerous tests with no real disgnosis. This past week Ive noticed it hurts my lower back to sit or lay on my right side (same side as the knot). Feels as if Im laying or sitting on something (like a toy or something hard) that is not there!! any ideas on what this could be? Thanks in advance for any information you can give me!   -Kayla
