What Could My Lower Back Pain Be?

These are the most common explanations we see:

Strains happen when muscles supporting the spine are overloaded. They are common, often painful for a few days, and usually improve steadily with gentle movement.

The small facet joints of the spine and the sacroiliac joints where the spine meets the pelvis can become stiff and irritated. This often causes one-sided pain and stiffness, and muscles nearby tighten to protect the area.

A rough guide: muscle pain tends to feel sore and tight and is tender to touch; disc-related pain is often deeper, worse with sitting and bending, and may travel into the buttock or leg. Many people have a bit of both. An exam, including movement testing and nerve checks, is the reliable way to sort it out.

Sometimes the main problem is that the low back and hips simply do not move as well as they used to. Long sitting, less activity, and age-related changes in the joints can all contribute. This kind of pain is often worst in the morning or after sitting and eases once you get moving. It responds well to regular movement and to care that restores motion and builds strength.

A small share of lower back pain comes from outside the muscles and joints. Pain with fever, burning with urination, or pain in the side and back that comes in waves may involve the kidneys or urinary tract. Back pain in someone with thinning bones (osteoporosis) after even a minor fall can be a small fracture. Back pain with unexplained weight loss or a history of cancer needs medical evaluation. These are uncommon, but they are exactly why a good exam includes screening questions.

When a nerve root in the low back is irritated, pain can travel down the leg with tingling or numbness. If that sounds like you, read sciatica relief and what sciatica pain feels like.

Usually not at first. For most mechanical lower back pain without red flags, imaging does not change the first steps of care, and findings like disc bulges are common even in people without pain. Imaging is more useful when symptoms are severe or worsening, when there are signs of nerve weakness, when red flags are present, or when pain is not improving as expected. If your exam points that way, we will explain why and help coordinate a referral.

• When did it start, and was there a trigger?
• Where exactly is it, and does it travel?
• What makes it better, and what makes it worse?
• Is it worse in the morning, at the end of the day, or at night?
• Have you had it before, and what helped?

At Back Pain Center Wentzville, the exam is where guessing stops. We ask how your pain started and what changes it, test how your spine and pelvis move, and check reflexes, strength, and sensation. That tells us which structures are likely involved and whether you need a referral for imaging or medical care.

From there, chiropractic care is built around what we find: adjustments to restore motion, hands-on work for tight muscles, and rehab-style exercise to build support. Common questions about visits are answered on our FAQ page.

Often, yes. A stiff joint can make nearby muscles guard and tighten, and an irritated disc can make both joints and muscles more sensitive. That overlap is one reason a single label rarely tells the whole story. Care usually works best when it addresses the joints, the muscles, and the daily habits that load them, rather than chasing one sore spot.

People often try to diagnose their back pain by where it hurts. Location helps, but how the pain behaves is just as telling: what time of day it is worst, which movements provoke it, whether it travels, and how it has changed over time. That behavior is what a good exam pays close attention to, and it is why two people with pain in the same spot can need very different care.

Muscle strains usually need movement and time; joint stiffness responds to restoring motion; disc irritation calls for position and movement changes that calm it; and sciatica needs extra attention to the nerve. Figuring out which applies is the first job of your visit.

• Stay active with short, comfortable walks
• Change positions every 20–30 minutes
• Use ice or heat, whichever feels better
• Avoid heavy lifting and twisting while it is flared
• Write down what makes it better or worse to share at your visit

If none of these seem to fit, or several do, that is normal. Sorting out overlapping causes is exactly what a hands-on exam is for.

Many Wentzville-area patients come in after weeks of “waiting to see if it goes away.” If that is you, there is no need to keep guessing or self-diagnosing. A focused exam can give you a clear answer and a path forward. Learn more about back pain care.
