Your hairdresser mentioned it, or you saw it in a side-on photo. There is a rounded bump at the base of your neck, and every video you find says chin tucks. So which bump do you have?
You may see it called a neck hump, a dowager’s hump or a buffalo hump. This page sorts out which is which, who looks at each one, the signs that mean a doctor first, and what a physiotherapist tests when the cause is posture.
What is a neck hump?
A neck hump is a rounded bump where the base of the neck meets the upper back. It usually comes from one of three sources: a pad of fat, an upper back rounded by posture and weak back muscles, or vertebrae that have collapsed at the front. Each one has a different route, so the cause comes first.1,2
Key takeaways
- A neck hump usually comes from fat, posture or bone. You can have more than one.
- A pad of fat, often called a buffalo hump, is a question for your doctor. High cortisol and long-term steroid medicine are common causes.
- Lost height or sudden back pain after a small strain points to the bone. See a doctor first.
- A physiotherapist works on the posture part: back muscle strength, upper back movement and head position.
- Chin tucks do not shrink a pad of fat or reshape a collapsed vertebra.
First, the signs that mean a doctor, not this page
- Call 995 for sudden severe chest or upper back pain with breathlessness, sweating or feeling faint, or for neck or back pain after a fall or a car accident.
- Go to the emergency department now for new numbness between the legs, new trouble passing or holding urine or stool, new weakness in both legs, or hands that have turned clumsy.
- See a doctor the same day for sudden back pain after a small lift, cough or slip if you are over 50, have osteoporosis or take steroid tablets, or for neck or back pain with a fever, a past cancer or unexplained weight loss.
- See a doctor soon if the hump came with weight gain, a rounder face, stretch marks or easy bruising; if you take steroid tablets long term or HIV medicines; if you have lost height; or if the lump is hard, sore or growing.
None of these? Then the rest of this page is for you.
Fat, posture or bone?
| What you notice | Fat | Posture | Bone |
|---|---|---|---|
| What it is | A pad of fat at the base of the neck | An upper back rounded by how you hold it, with weak back muscles | Spinal bones collapsed at the front, adding to the curve |
| What often comes with it | Weight gain, a rounder face, stretch marks, easy bruising, steroid tablets | Long hours at a desk or on a phone, an ache that builds through the day | Lost height, back pain after a small strain, osteoporosis, steroid tablets, age over 50 |
| When you stand tall or lie flat | The lump stays | The curve eases, at least partly | The curve changes little |
| Who first | A doctor | A physiotherapist | A doctor, then a physiotherapist |
Use the table as a guide, because you can have more than one. Pressing on the lump will not settle it. The fat in a buffalo hump can feel firm enough to pass for spine.3 A separate lump under the skin, such as a cyst or a lipoma, is also one for your doctor.
If it is fat: a question for your doctor
A buffalo hump is a pad of fat at the back of the neck. The most common cause is too much cortisol, from Cushing syndrome or from long-term use of steroid medicine. Some HIV medicines, obesity and rarer conditions such as Madelung disease can also cause it.2,3 Your doctor looks for the cause and may refer you to an endocrinologist, a hormone doctor.
If you take a prescribed steroid, put your questions about it to the doctor who prescribed it. Any change to it is that doctor’s decision.3 Weight loss may help if obesity is behind it, though you cannot choose where the fat comes off. Surgery is uncommon, and a surgeon decides who is suitable.3 We found no evidence that exercise shrinks this pad of fat, so we would send you to your doctor.
If it is bone: a doctor first, then us
With osteoporosis, a spinal bone can collapse at the front, sometimes after something as small as a cough. Each fracture adds to the curve, by about 3.8 degrees in the study a 2020 review cites.1 The same review found vertebral fractures in about 40% of people with hyperkyphosis, so many people with a rounded upper back have none.1
Height is a clue. In 985 postmenopausal women with osteoporosis followed for three years, those who lost more height were more likely to have a new spinal fracture, though no single figure confirmed one.4 If the height on your health screening has dropped, ask your doctor about it, including whether you need a spine X-ray or a bone density scan.
Until your doctor has checked, leave out sit-ups, toe touches, and bending or twisting under load.7 After a confirmed fracture, the back muscles, balance and bending are what we train. That is covered in spinal compression fracture.
If it is posture: the part a physiotherapist treats
In older adults, weaker back muscles go with a bigger upper back curve.1 The research on exercise is real and modest. A review of 13 studies found 8 reported improvement in at least one posture measure, with too little good data to pool.6
One trial took 99 adults aged 60 or older with a curve of 40 degrees or more. They did physical therapist-led spine strengthening and posture training three times a week for six months. Their curve ended about 3 degrees smaller than a comparison group’s, and self-image scores improved. Walking speed and other physical function tests showed no difference.5
What you can start at home
If none of the doctor signs above apply, and only then, these three are a common starting point.8
- Chin tuck. Sitting or standing tall, slide your chin straight back without looking down. 3 sets of 10, daily.
- Shoulder blade squeeze. Draw the shoulder blades back and together without shrugging. 3 sets of 10, daily.
- Doorway chest stretch. Forearms on the door frame, step through until the chest stretches. Hold 20 to 30 seconds, 2 to 3 times a day.
Stop if pain or tingling travels down an arm, and get that checked. Neck ache from long desk hours is covered in office syndrome and tech neck.
Why three months of chin tucks have not moved it
The thinking goes: it is posture, so stand straighter and do the exercises in the video.
Three months in, you still feel for it when you tie your hair up. Your collar sits differently at the back. Someone took a family photo from the side at reunion dinner, and you asked them to delete it. The posture corrector you bought is in a drawer. Your health screening is in March, and you do not know whether this is something to raise.
Chin tucks do not touch two of the three. They bring the head back. They do not shrink a pad of fat, and they do not reshape a vertebra that has collapsed at the front. Even for the posture kind, the trial above trained the back muscles for six months. Has anyone asked about your steroid tablets, compared your height with your last screening, measured the gap between your head and the wall, and timed how long your back muscles hold? If not, you are exercising against a cause nobody has named.
What a physiotherapist does with it
Finding the real problem is half the battle. Treating it is the other half.
At the Assessment & Treatment, a physiotherapist asks when you first noticed it and what came with it, then tests: the gap between the back of your head and the wall, your height, how far your upper back extends, how long your back muscles hold, your shoulder blade control and chest tightness, and your balance and chair stands if you are older. If anything points to fat or bone, we tell you and write to your doctor. Blood tests, X-rays and bone density scans are theirs.
Most of the 45 minutes is treatment: hands-on work for the upper back and neck, then a strengthening program for the back muscles that we measure at each review. Most people with a posture cause are in Stage 2 or 3 of the four. After a fracture, you start at Stage 1, on your doctor’s advice. You leave knowing which stage you are in, what is limiting you, and a written plan.
More on physiotherapy for neck pain and pain between the shoulder blades. Every appointment is one to one with your physiotherapist for the full 45 minutes, at five clinics: Orchard, Tampines, Serangoon, Tanjong Pagar and Jurong East. Bring any X-ray or bone density report, your last health screening, and a list of your medicines.
Questions about neck humps
What causes a neck hump?
Usually one of three things: a pad of fat at the base of the neck, an upper back rounded by posture and weak back muscles, or spinal bones that have collapsed at the front, often with osteoporosis. A doctor looks into the fat and the bone. A physiotherapist works on posture and strength.
Is a dowager’s hump the same as kyphosis?
Dowager’s hump is the older, everyday name for an increased forward curve of the upper back. The medical terms are kyphosis and, when the curve goes beyond the usual range, hyperkyphosis. One 2020 review proposes 50 degrees or more on a standing X-ray as the definition of hyperkyphosis.
What is the difference between a buffalo hump and a dowager’s hump?
A buffalo hump is a pad of fat at the base of the neck, most often from high cortisol or long-term steroid medicine. A dowager’s hump is the spine curving forward in the upper back. The fat can feel firm, so pressing on it does not reliably tell them apart. A doctor can.
Do chin tucks help a neck hump?
Chin tucks train you to bring the head back over the shoulders, which suits a hump from posture. They do not shrink a pad of fat or reshape a collapsed vertebra. If you have lost height, had sudden back pain, take steroid tablets, or have gained weight with the hump, see a doctor first.
How long does a neck hump take to improve?
Expect months of exercise, and no one can promise how much the curve will change. In one trial, older adults trained three times a week for six months, and their curve ended about 3 degrees smaller than a comparison group’s. Fat and bone causes depend on what your doctor finds.
What causes a neck hump in women?
The same three causes apply. Bone is the one to check earlier in women after menopause, because osteoporosis is a common reason for spinal bones to collapse. If you have lost height or had sudden back pain after a small strain, ask your doctor about it, including whether you need a bone density scan.

Where are you with this right now?
1. It is settling on its own
If none of the doctor signs apply, you have cut your long desk stretches, the ache has eased over the months, and the gap between your head and the wall is holding steady, keep going. You do not need us for this, and we would rather say so.
2. It has stopped improving
You have adapted without noticing. You choose high collars, you stand at the back of photos, and you have stopped reaching up to the top shelf without bracing your back.
Pain is the first thing to leave. Movement and strength are the last things trained back, and most people stop before that part is done. That is the gap worth measuring, and it is not measured by how you feel on the day.
The Stalled Recovery Review is three appointments over three weeks with the same therapist, because what a spine does under load cannot be read in one visit. The first finds what is limiting it. The next two measure how it responds.
3. You have had surgery, or you have a date
Recovery after an operation has a shape, and knowing which stage you are in tells you whether you are on it. After vertebroplasty, kyphoplasty or spinal fixation, bring your surgeon’s protocol and we work inside it. See physiotherapy after surgery.
All of it runs on the same four stages. The Phoenix Recovery Protocol explains what each stage works on and what you have to meet to move up. No referral needed to start.
Next step
Find out which stage you are in
Pain is the first thing to leave. Movement and strength are the last things trained back, and most people stop before that part is done. One Assessment and Treatment is a single 45-minute appointment at $230, nett, no GST. Your therapist finds what is actually limiting you, treats it in the same appointment, and you leave with your current stage and a written plan.
