So, your back hurts. Yeah, I get it. And probably more than you realize, your back is moving literally all the time. Like, seriously, every tiny thing—standing up, sitting down, brushing your teeth, laughing at a dumb joke, even breathing—your back is part of it. And when it hurts, even these small things feel like a chore.
If you’ve noticed lower back pain on one side when brushing teeth, you’re not alone. That little twinge can make a simple morning routine feel impossible, and it’s a signal that your back is trying to tell you something.
It’s natural to start thinking, “Okay, maybe I just need to rest a bit, or slap an ice pack on it…” But then, a little voice in your head asks, “What if it’s something serious? What if it’s not just a strain?” And that’s fair. Most of the time, back pain isn’t dangerous, but, let’s be real, it can really mess up your day, your week, maybe even months if it sticks around.
Back pain is crazy common. Like, millions of people deal with it at some point. And physical therapy is basically the first thing doctors suggest for pretty much any type of back pain. But just because it’s common doesn’t mean you should shrug it off. Paying attention matters.
How to Figure Out Why Your Back Hurts
Everyone’s pain is a little different. Some people get a dull ache, some get a sharp stabbing pain, some feel burning, some feel tightness. But your symptoms actually tell you a lot.

Here are the usual ones people notice:
- Shooting, burning, or aching pain that doesn’t quit or comes back even after icing or popping a painkiller.
- Stiffness or tightness, especially after sitting too long, standing too long, or lying down weirdly.
- Trouble sleeping. Seriously, lying down can be torture.
- Weakness in your legs, or numbness/tingling. That’s when your back is kind of talking to your nerves.
The key is: where it hurts, how it started, and how bad it is. Those little details are huge for figuring out what’s going on.
When and How Your Pain Started
Doctors always ask, “How did this start?” for a reason. Did it come on suddenly? Maybe after lifting a heavy box, bending weirdly, or doing some intense activity you’re not used to? Or has it been creeping in over weeks, months, or years?
Sometimes pain just shows up randomly after your routine changes—maybe you started sitting at a desk more, or you moved furniture in a weird way. Figuring out the onset helps decide if it’s short-term (acute) or long-term (chronic).

Acute vs. Chronic Pain
So, here’s the deal:
- Acute pain is short-term, usually under six weeks. It can be sudden, sharp, annoying, maybe even scary the first time it hits. But often it responds to ice, heat, over-the-counter meds, and some rest. Usually, it starts getting better in a couple of weeks.
- Chronic pain hangs around. More than six months. Sometimes it sneaks up slowly, sometimes it comes in waves. Chronic pain is trickier because your body gets used to being in pain, and muscles can tighten, making everything worse.
Most back pain people get is nonspecific acute pain. That just means “we don’t know the exact cause, but it’s not usually dangerous.” But chronic pain deserves attention because it can snowball into something that messes with your life if ignored.
Where It Hurts
Your spine isn’t just one thing—it’s 33 little bones called vertebrae, plus discs, nerves, muscles, ligaments…a whole complicated machine. Where it hurts tells a lot.

Lower Back Pain
Lower back pain is by far the most common. That’s because your lumbar spine carries most of your weight.
You might feel:
- Stiffness that makes standing up straight or bending annoying.
- Muscle spasms if you’ve strained something—ouch, those are brutal.
- Pain shooting down your leg—sciatica. Nerve stuff. Not fun.
Lower back pain usually gets better with rest, gentle movement, and sometimes physical therapy. But if the pain radiates down the leg, it’s a good idea to get it checked.
Upper or Middle Back Pain
The thoracic spine is less bendy because your ribs are attached, so pain here is less common. Usually, it’s from a strain or bad posture.
Symptoms:
- Burning or sharp pain that comes and goes.
- Tightness in your muscles.
Upper back pain is usually less serious than lower back pain, but don’t ignore persistent pain.
How Bad Is It?
Pain is annoying, but some pain is more than annoying. Doctors usually use a 1–10 scale:

- Mild (1–3): It’s there but you can still move around.
- Moderate (4–7): It interrupts your day, wakes you at night, makes life harder.
- Severe (8–10): You can barely move, maybe can’t sleep, normal life is basically impossible.
Mild pain often goes away on its own. Moderate and severe pain? You might need help.
Nonspecific vs. Specific Back Pain
Here’s a quick split:
- Nonspecific pain: most back pain is this. There’s no diagnosed disease causing it, usually just muscle strain or general wear-and-tear.
- Specific pain: caused by something identifiable, like a fracture, a slipped disc, cancer, or a neurological issue.
Even if it’s likely nonspecific, keeping an eye on it is smart—sometimes things start small and get worse.
When You Should Seek Treatment
Back pain is tricky. Sometimes it’ll fade on its own, but sometimes it needs care. You should see a spine doctor or physical therapist if:
- Pain lasts more than two weeks and isn’t improving.
- Pain keeps coming back over time.
- It interferes with daily life.
Getting help early can stop it from turning into a chronic problem.
Physical Therapy: Why It Works
This is the big one. Movement helps healing. Physical therapy is literally about moving in the right way.

PT uses:
- Exercises to strengthen your back and core
- Manual therapy (like targeted massage or adjustments)
- Education on posture, movements, and how to avoid reinjury
Studies show PT works for almost every type of back pain, and in most cases, you don’t even need a doctor’s referral. Some clinics even have programs specifically for chronic back pain, where they guide you step by step.
Home Remedies and Exercises
You don’t always need to go to a clinic right away. Some stretches and exercises at home can make a big difference. The key is moving the muscles around your lower back and hips:
- Pelvic tilts: helps loosen up tight muscles
- Lower trunk rotations: works on flexibility
- Knee-to-chest stretches: eases lower back tension
Try stuff slowly, see what feels better. If you’re unsure, a PT can make a plan so you’re not making things worse.
When It’s an Emergency
Most back pain isn’t an emergency. But there are red flags:
- Sudden severe pain, weakness, or numbness
- Losing control of bladder or bowels
- High fever
- Severe stomach pain
- Unexplained weight loss
- Pain after a fall or serious blow
If you notice any of these, go to the ER. Don’t wait.

Don’t Ignore It
Even if it’s “just annoying,” don’t let back pain linger. Two weeks, repeated flare-ups, or pain messing with life? Time to take it seriously.

Doctors or PTs can:
- Listen to your symptoms
- Figure out what’s really going on
- Help with exercises, stretches, and treatments that actually work
Physical therapy is the first thing most orthopedic doctors suggest, and for good reason—it works.
Wrapping It Up
Okay, so here’s the thing—back pain sucks. Like, it really does. But most of the time, it’s not a sign that something terrifying is happening in your body. Usually, it’s muscles, posture, or nerves just being finicky, and yeah, movement, stretches, and a little care can fix it. The key is paying attention early, not just “hoping it goes away” and ignoring it until it’s unbearable.
If it’s mild, keep moving, stretch, maybe do some of those pelvic tilts or trunk rotations we talked about. If it’s more than that—moderate, severe, chronic—don’t wait: go see a physical therapist, a spine specialist, whoever you need. Physical therapy isn’t just for injuries—it’s literally the thing most doctors suggest first for a reason.
