Tailbone pain is one of those problems that sounds minor until you have it. Then every chair becomes a negotiation. It is common in people who sit for long hours, and it often gets worse the longer the workday goes.
The good news is that most tailbone pain improves with simple changes to how and how long you sit. This post explains why it happens, what to change at your desk, and when it needs a professional look.
What the Tailbone Is
The tailbone, or coccyx, is the small triangle of fused bones at the very bottom of the spine. When you sit upright, most of your weight rests on your sit bones (the two bony points at the base of the pelvis), and the coccyx takes only part of the load. When you lean back or slump, more of your weight rolls onto the coccyx itself.
Pain in this area has a medical name: coccydynia. It is more common in women, partly because of pelvic shape and partly because childbirth can strain the area.
Why Sitting Makes It Hurt
The usual causes are:
- Prolonged pressure. Hours of sitting, especially slumped with the pelvis tilted back, keep steady pressure on the coccyx and the joint above it.
- Hard or narrow seats. Car seats, bleacher seats, bike saddles and firm kitchen chairs concentrate the load.
- A fall or impact. Landing on your backside, even weeks ago, can bruise or strain the area and leave it sensitive to pressure.
- Childbirth. The coccyx moves during delivery and can stay sore afterward.
- Rapid weight change. Weight loss can reduce padding over the area, and weight gain increases the load when sitting.
A typical pattern: the pain is worse when sitting, sharpest when moving from sitting to standing, and better when standing or walking.
Change How You Sit
These changes help most people within days:
- Sit tall or lean slightly forward. That moves your weight onto the sit bones and off the coccyx. Slumping into the back of the chair does the opposite.
- Use a wedge or cutout cushion. A cushion that is thicker at the front, or one with a gap at the back (often called a coccyx cushion), lets the tailbone hang free. Ring shaped "donut" cushions are often less helpful for the coccyx than a back cutout, because they can still press on it.
- Shift your weight. Lean onto one buttock, then the other, every few minutes. It sounds silly, but it relieves constant pressure.
- Get up often. Every 30 to 45 minutes, stand for a minute or two. Our post on how long you should sit before taking a break explains why short frequent breaks beat one long one.
- Try a standing stretch of the day. Alternating sitting and standing work, if you have the option, cuts total pressure time a lot.
Gentle Stretches That Help
Tight muscles around the pelvis can pull on the area and add to the ache. These are gentle, and none of them should be pushed into pain.
1. Seated Figure Four
Sit tall, cross your right ankle over your left knee, and lean forward slightly with a straight back until you feel a stretch in the right buttock. Hold 30 seconds, switch sides.
2. Standing Hip Flexor Stretch
Step one foot back into a short lunge, tuck the pelvis slightly, and push the back hip gently forward. Hold 30 seconds a side. Tight hip flexors tilt the pelvis and change how load falls on the base of the spine. Our lower back stretches for desk workers cover this one in more detail.
3. Child's Pose
Kneel, sit back toward your heels, and stretch your arms forward on the floor. Breathe slowly into your lower back for 30 to 60 seconds. If sitting back hurts the tailbone, keep your hips higher.
4. Cat Cow
On hands and knees, slowly round the back, then let it sag gently, 8 to 10 times. This moves the whole spine, including the lowest joints, without loading the coccyx.
| Stretch | Time | Targets |
|---|---|---|
| Seated figure four | 30 s each side | Glutes, piriformis |
| Standing hip flexor | 30 s each side | Front of hip, pelvis tilt |
| Child's pose | 30 to 60 s | Lower back, pelvic floor |
| Cat cow | 8 to 10 reps | Whole spine mobility |
Other Things Worth Trying
- Cold or heat. Ice for 15 to 20 minutes in the first days after an injury, then heat to relax tight muscles. Use whatever feels better.
- Over the counter pain relief. Ibuprofen or paracetamol can help in the short term if they are safe for you. Check with a pharmacist if you have other conditions or take other medicines.
- Avoid constipation. Straining puts pressure on the area. Fiber and water help.
- Pelvic floor physiotherapy. For pain that lingers, a physiotherapist who works with the pelvic floor can assess muscle tension around the coccyx and treat it directly.
When to See a Doctor
Most tailbone pain settles in a few weeks to a few months. See a doctor if:
- The pain started after a hard fall or accident
- It has lasted more than about eight weeks or keeps getting worse
- You have numbness, tingling or weakness in the legs
- You notice changes in bladder or bowel control (this needs urgent care)
- There is fever, a lump, swelling or redness near the area
- You have unexplained weight loss or pain at night that does not ease with rest
A doctor can check for a fracture, a cyst, or other causes, and discuss options like injections when simpler measures do not work.
Where Desk Stretches Fits
Desk Stretches is the iPhone app we build for people who sit for work. It reminds you to get up and walks you through short guided stretches for the neck, back and hips, which suits the "move often, take pressure off" part of the fix.
To be honest about the limits: the app does not diagnose tailbone pain, and stretching does not heal a fractured or dislocated coccyx. If your pain fits any of the warning signs above, see a doctor first. For the everyday sitting kind, the combination that works is a better sitting position, a cushion and frequent movement, and the app helps with the third part.
The Short Version
- Tailbone pain from sitting usually comes from steady pressure on the coccyx, often made worse by slumping.
- Sit upright or slightly forward, use a wedge or cutout cushion, and stand up every 30 to 45 minutes.
- Gentle hip and glute stretches can ease the surrounding tension.
- Most cases improve within weeks to months.
- See a doctor after a fall, if pain lasts beyond about eight weeks, or with any nerve, bladder or bowel symptoms.
