Ouch, my tail bone!

I have posted about my strained back muscle earlier. And it did get better after about 4weeks of rest. So it really took me off the pole for a solid month that I will have build up my upper body strength all over again. And I have one other problem. I think I hurt my tail bone real good when I first started doing layback or bat to slide down to elbow stand and handstand. All those moves that involves the contact with my tail bone. At some point, I could not let my tail bone have contact with the pole. Not just that, I could not even do sit ups on the floor becasue my tail bone hurts so much. It has been 2~3 months since I last did the layback move and my tail bone still hurts slightly if I sqeeze my glutes. So I am scared of doing this move again. How do you keep yourself from hurting your tail bone doing the layback? Any tricks and secrets you would share?
