Pain in the Coccyx can make sleeping difficult while sitting and bending can also be uncomfortable. Directly sleeping on your back or stomach may apply even more pressure to the spine. It’s suggested that sleeping on your side and placing a pillow between your knees is the best way to ease discomfort. Again, what works for one person may not work for you. An experienced spine specialist can administer an array of alternative and supportive medical treatments that may rid your pain.
