Hello there,,,,,any pain which manifests itself for more than 3 months should be taken seriously....tailbone/coccygeal pain is particularly a deep seated pain and can be quit irritating,,,,however to find out weather it is coccygeal pain or a strain around the structures a proper and detail assessment is necessary.
Next Steps
visit an Orthopadecian/musculoskeletal Physio.
xrays usually are not very informative hence manual assessment is necessary.
Health Tips
1) Avoid prolong sitting
2) Avoid sitting on hard surface
3) use a Round Ring Pillow to sit...or even while driving if you can to ease the preassure
4) Sit in hot water bath does bring temporary relief
5) OTC antiinflammatory medication or prescription medicine of serriatiopeptidase can bring relief.
do resort back to me with any furthur queries
Regards & Take care.
