Pain on the right side of the tailbone?

Hi there! Degenerative disc disease is an insidious condition. What you are experiencing is the effects if the degeneration progressing. The reason that it is on the right side only, is that is the side where you have compression of one or more of the nerves. You do not necessarily have to have pain or discomfort down your leg. Your pain and discomfort is directly related to exactly where the nerve compression is occurring. My advice would be to seek out a doctor that specializes in disorders of the spine. I most definitely can empathize with you. I just went through spinal surgery with fusion of 5 vertebrae. This was after years of degeneration and also a structural problem. Go find the best doctor that you can, but do not let them jump to a surgical procedure. There are other treatments that they can try first. I hope that this has been helpful to you. Feel better soon and best of luck to you.
