Why It Happens

The baby's head pressing on the sacrum and the relaxin hormone loosening joints around the coccyx can cause a sharp or dull ache at the base of your spine.

Safe Home Remedies

Use a donut pillow or V-shaped cushion when sitting.
Avoid sitting on hard surfaces for long periods.
Apply ice packs or warm compresses to the area.

⚠️ When to Contact a Doctor

Clinical Questions & Answers

Q1: Why does my tailbone hurt when sitting?

Sitting puts direct pressure on the loose, tender joints of the coccyx.

Q2: Can tailbone pain be relieved by physical therapy?

Yes, pelvic floor physical therapists can release tight muscles around the tailbone.

Q3: Will tailbone pain affect delivery?

You may want to avoid birthing on your back, which compresses the tailbone further. Side or hands-and-knees positions are better.
