If you drive the 405, the 5, or the 55 during rush hour, you already know the feeling: you get out of the car after 50 minutes and your lower back feels stiff, achy, and about ten years older than you are. Then you sit at a desk for eight hours and do it all again on the way home.
This is one of the most common complaints we hear at [Clinic Name]. Here's what's actually going on, and what you can do about it.
Why sitting is hard on your back
Sitting isn't inherently damaging. The problem is sustained, unvaried sitting.
When you sit for long stretches, three things happen. Your hip flexors shorten and pull on your pelvis, which changes the position of your lumbar spine. Your glutes and deep core muscles stop firing, so the smaller muscles around your spine take over work they aren't built for. And the discs in your lower back sit under steady compression without the gentle load-and-unload cycle that movement provides.
Driving adds a few wrinkles. Most car seats put your hips lower than your knees, which rounds the lower back. Your right leg holds a fixed position on the pedals, so one side of your hip works differently than the other. And every brake tap and lane change adds small vibrations that fatigue the muscles trying to stabilize you.
The pattern we see most often
People assume a "weak back" is the culprit. More often, we find weak glutes and a stiff hip, with the lower back compensating for both. Treat only the back and the pain usually comes back. Address the hip and glute, and the back often calms down on its own.
Four things that help before you call anyone
Change positions every 30 to 45 minutes. Not a perfect posture - just a different one. Stand up, walk to the kitchen, shift how you're sitting.
Fix your car seat. Raise the seat so your hips are level with or slightly above your knees. Bring the seat back closer to upright, around 100 to 110 degrees. Add a small rolled towel at your lower back if the seat has no lumbar support.
Try standing backbends. Hands on your lower back, gently arch backward 10 times. This reverses the flexed position you've been in. Most people feel relief immediately.
Wake up your glutes. Glute bridges - 2 sets of 15 - before you get in the car in the morning and after you get out in the evening.
When to see a physical therapist
Self-management works for a lot of people. Come see us if:
- The pain has lasted more than two or three weeks
- It travels into your buttock, thigh, or below the knee
- You feel numbness, tingling, or weakness in a leg
- It's affecting your sleep or your workouts
- It keeps coming back every few months
That last one matters more than people realize. Recurring back pain usually means an underlying movement problem was never addressed - the flare-up calmed down, but the cause didn't.
In California you can see a physical therapist directly, without a physician referral. A first visit typically includes a movement assessment, hands-on treatment, and a specific exercise plan you can do in a few minutes a day.
At Core Performance Physical Therapy, if you are utilizing our cash based services, you can get treatment sometimes the day of with no referral required. If you are utilizing your insurance, a referral is required.
