[|Human|] I am 40 years old and have recently dscovered a lump at the bottom of my tailbone. The pain is greater when I sit or ride for long periods of time. Do you know what this could be or why all of a suddn I am having so much pain. Thank You, Penny Jackson
[|AI|]  Hi, The bone at the base of your spine is the coccyx and is quite sensitive if damaged. You may have inadvertently bruised your coccyx. Paracetamol and ibuprofen will help the pain. With rest the pain should subside. Alternatively, you may have a colonial cyst which has become inflamed or infected. This is a small cyst commonly found at the base of the spine which can cause pain when inflamed. I suggest you see your doctor who will be able to examine you and confirm the cause of your pain.
