Has anyone had one of these? I made an appointment to see the docter, but the earliest I could get was 2 weeks away. I have: Consant knot in my lower back Cramp/burning in my calf all day Can't sleep through the night If I lie down and move slightly I get pain shooting down my leg Very hard to stand up/sit down Just wondering if anyone had something similar and could share their symptoms/treatment. I am really scared I'm going to need surgery. I'm only 20. I have already been to 2 docters, neither took an xray, the first one didn't even touch or look at my back.
