If you have sciatica, you probably have two questions. How long is this going to last? And is there anything I can do besides wait?
The good news is that the research on both is clearer than most people expect.
Most of the change happens early
A large study in UK primary care followed 609 people with back related leg pain for a year. For every group, most of the improvement in pain and function happened in the first four months (Stynes et al., 2018).
That same study is honest about the rest. A year later, somewhere between about a quarter and under half of people described themselves as recovered or much better, depending on the type of leg pain they had. So waiting it out works for some people. For a lot of people, it doesn't finish the job.
Your disc can heal on its own
This surprises almost everyone. When researchers pooled 31 studies covering 2,233 people treated without surgery, about 70% of lumbar disc herniations shrank or disappeared on their own (Zou et al., 2023).
The bigger herniations actually did best. Sequestered herniations, where a piece of disc breaks free, were reabsorbed about 88% of the time. Small bulges were reabsorbed only about 13% of the time. Most of that healing happened within six months.
So a scary MRI report doesn't mean you're headed for surgery. Your body is often already working on it.
What helps while you heal
In a randomized trial of 192 adults with back related leg pain, people who got hands on spinal care plus a home exercise program did better at 12 weeks than people who did the home exercise program alone (Bronfort et al., 2014).
At one year, the difference in leg pain was no longer statistically significant. But the hands on group still reported more overall improvement, more satisfaction, and less medication use.
That matches what we see in the office. The hands on work helps you get moving sooner. The exercises are what keep you there. You need both, and you need a plan that fits how you actually spend your day.
When sciatica is an emergency
Go to the emergency room, not a clinic, if you notice any of these (NHS Scotland):
- Numbness in your groin, genitals, or around your bottom
- New trouble starting to pee, or not feeling yourself pee
- New loss of bowel control
- Leg pain or weakness in both legs, or weakness that keeps getting worse
These can be signs of cauda equina syndrome, which needs urgent care.
What we do at FRI
We start by finding out what kind of leg pain you actually have, because not all leg pain is sciatica. Then we build a plan around your week: the hands on care that gets you moving, and the specific exercises that keep the nerve calm while your disc heals.
If you want to talk it through first, book a complimentary 20 minute consultation.
