Most people picture scoliosis as something that begins in childhood, when the spine curves during a growth spurt. That is one path. Another path starts later. In adults, a curve can appear or worsen as discs thin, facet joints wear, and ligaments loosen over many years. Clinicians often call this degenerative scoliosis. The curve may be mild at first, and many people notice it only when pain, stiffness, or a change in posture makes them look more closely.
This changes how you prepare. A teen's exam centers on whether the spine is still growing. An adult's exam centers more on symptoms and how they behave when you stand, walk, and sit. If you are an adult with a sideways lean, the useful question is not only 'Do I have a curve?' but 'When did this start, and what has it done since?'
What to write down before you go
Before any visit, note three things. First, when you first noticed the lean, uneven shoulders, or a hip that sits higher, even if you cannot date it exactly. Second, where the pain sits. Is it only in the low back, or does it travel into the buttock, thigh, or leg? Third, what makes it better or worse. Many people find that standing for a long time or walking brings symptoms on, while sitting or leaning forward eases them. Describe that pattern in your own words. A sentence such as 'my left leg gets heavy after a few minutes at the grocery store' gives an examiner far more to work with than 'my back hurts.'
Also note any change in strength, numbness, or balance. A foot that drags, a new stumble, or numbness in the groin or inner thighs is not a question for a routine appointment next month. Those signs call for prompt medical care. Sudden bladder or bowel changes, or new weakness in both legs, call for emergency care right away.
What an examiner should check
A thorough visit for an adult lean usually includes the history described above, a look at posture and movement, and a nerve screen. The nerve screen covers reflexes, strength in each leg, and sensation in each foot and leg. Ask whether those checks were done and what they showed, in plain terms, before you leave.
Imaging is the next topic. Standing X-rays are a common way to measure a curve and see how the spine lines up under your weight. If older films exist from an injury, a checkup, or a school screening, bring them or ask where they are kept. Comparing old and new images shows whether the curve has actually changed, which is often more useful than a single picture. Ask whether the office will request prior images and whether it will send a copy of the report to your primary care doctor.
Comparing where you can go
In the St. Louis metro, you have several starting points: your primary care doctor, a physical medicine or spine practice, or an orthopedic or neurosurgical spine clinic. Each has a different role. Some order imaging and manage pain. Others focus on physical therapy or bracing. Spine surgeons usually get involved when nerve symptoms are significant or a curve is large and progressing. Call any office and ask which of these services it provides, whether it can refer you elsewhere if needed, and whether your insurance requires a referral first.
Ask what happens next if your symptoms stay the same. A useful answer names a follow-up interval, lists the changes that should prompt an earlier return, and explains which activities are safe to keep up in the meantime. Write those answers down. You will want them when you call back later and cannot remember the details.
Putting it together
Adult scoliosis is usually understood through a combination of history, examination, and comparison over time, not through one measurement on one day. Your job before a visit is modest. Write down when the lean began, where the symptoms go, and what brings them on. Gather any old images you can find. Then choose an office that can examine your nerves, obtain imaging when it is needed, and tell you in writing what to watch for. This explainer cannot tell you whether your spine is curved or what treatment fits your case. Only an in-person examination can answer that, and it is worth getting one if the lean, the pain, or the leg symptoms are changing.
