text: i have a pain in cocxiz lower part of my back bone how will get relieve from there i cant sit for a long time.   stretch you legs and do exercises take a walk lower back pain is the worst kind i know i have experienced it my self try leg lifts as these can help also see if you can find some one to give you a masage its not the bone that gives you pain but the muscles around it. lay on your back and bring your knees one at a time up to your chest do at least 8 times and hold for 8 seconds do this every day for two weeks and you should be feeling beter.
