Hello Doctor, My tailbone has been killing me for the past few months. The pain is a heavy - pressure kind of pain. My MD had X-rays taken, this showed nothing. I saw him the other day and told him I still have this pain. He said he is not sure what else he can do for me other than use a donut when sitting. I sit at home on a nice soft leather recliner, my tailbone still kills me. I end up leaning on my side when I sit, but when I get up, the pressure/pain is terrible. I notice the pain/pressure even when I walk. Hurts when I sleep, especially turning over. I do want to mention that I had a colon resection back in 2005. I had a tumor in my rectum. The surgeon could feel my tumor, that is how low it was. I am worried I may have another tumor. PLease give me some advise what I need to do. THANK YOU FOR YOUR TIME!
