Hi Dear, Welcome to HCM. Understanding your concern. As per your query you have persistent lower back pain and tail bone pain. Well there can be many reasons for symptoms you mention in query like traumatic injury to the area of tailbone like a sudden blow or fall, long hours of sitting in wrong posture or bending to lift heavy weight .

You can be advised to take anti-inflammatory painkiller like Ibuprofen, take muscle relaxants like Chlorzoxasasone, warm compresses. you can also be advised physiotherapy ,which will be very helpful.
