Your symptoms are suggestive of coccydynia (tailbone pain), commonly caused by prolonged sitting, repetitive pressure over the coccyx, poor posture, or occasionally a minor unnoticed injury. I recommend using a coccyx (U-shaped) cushion, avoiding prolonged sitting, taking frequent breaks, warm sitz baths, and a short course of pain medication if suitable. As your symptoms have persisted for 3–4 months, an orthopaedic evaluation is recommended to confirm the diagnosis and rule out other causes.
Next Steps
Consult an Orthopaedic Surgeon for clinical examination. An X-ray of the sacrococcygeal region (preferably sitting and standing lateral views) may be required. If symptoms persist despite conservative treatment, further evaluation such as an MRI may be advised.
Health Tips
Avoid sitting continuously for long periods. Stand and walk for a few minutes every 30–45 minutes. Seek medical attention immediately if you develop fever, swelling, numbness, weakness, bowel/bladder symptoms, or unexplained weight loss.
