Having a dull ache around my tailbone area, feels like I've banged it but I haven't, what could this be? Worried it's bone cancer I'm 28 female. :)

Coccydynia. Tail bone pain usually occurs secondary to a fall or sitting on hard surfaces. First thing to try is a donut pillow which takes the pressure off of your tailbone. Ice or non steroidal s may also help. If no response then get it checked but cancer would be rare.
