What It Is

Coccydynia is pain in the coccyx (tailbone), the small bone at the base of the spine near the top of your bottom (NHS, 2025). It is often associated with tenderness at the tip of the tailbone. The pain may feel dull and achy most of the time, with occasional sharp pains. It is often worse when sitting, when going from sitting to standing, when bending forward or when having a poo (NHS, 2025). It commonly occurs after an injury, but there are times when it comes on for no known reason. Coccydynia can also be referred pain from the lower back (Lirette et al., 2014).

Coccydynia Anatomy

The coccyx sits at the lowest part of the spine and is thought to be what remains of a tail. The name comes from the Greek word for cuckoo, because from the side the coccyx looks like a cuckoo's beak (Lirette et al., 2014). It is a small triangular bone made up of three to five fused segments (Lirette et al., 2014; Cleveland Clinic, 2023). The front of the coccyx is slightly concave (curved inward), while the back is slightly convex (curved outward). The coccyx joins the sacrum (the bone above it) at a joint, and several muscles and ligaments attach to it, including the coccygeus muscle and fibres of the gluteus maximus (buttock) muscle. These help to support the pelvic floor (Lirette et al., 2014).

One of the most common ways to cause coccydynia is a fall, typically when you land on your backside. A common example is slipping down some stairs, where the step catches your tailbone. Another is slipping on ice and landing on your tailbone. Other common causes include pregnancy and childbirth, and repeated or prolonged strain, for example from sitting for a long time while driving or cycling (NHS, 2025). If you fall heavily, a coccyx fracture may need to be ruled out. Even if a fracture is found, most coccyx injuries are managed with pain relief and by avoiding pressure on the tailbone (NHS Grampian, 2022).

Tailbone pain may improve after a few weeks, but it can sometimes last longer (NHS, 2025). Most people get better with simple home treatment (Cleveland Clinic, 2023), so it is worth sticking with the steps below.
