Sciatica and leg symptoms
Why stretching doesn’t always help sciatica
Why a stretch can feel different from muscle tightness
Sciatica typically involves irritation of nerve roots in the lower back that contribute to the sciatic nerve. Positions that stretch the back of your thigh can also change how those nerves are loaded. A symptom during one stretch is only one clue. Its location, how far it travels, and how quickly it settles give us more information. [1]
What I look at in the clinic
I’ll ask you to describe where the symptoms start and where they go. I may check leg strength, sensation, and reflexes, and see how symptoms respond to movements or positions you use every day. If you dread sitting through a meeting, how you feel while sitting and as you get up matters more to us than how far you can stretch. [2]
What we can change
We may start with a way to make sitting or walking more manageable and build back toward the activity you’re missing. I’ll ask whether symptoms travel farther down the leg, ease back toward the hip, or take longer to settle after a change. That response helps us choose what to try next. A trial found better disability scores after early physical therapy for recent-onset sciatica. A broader review found mixed evidence across different types of physiotherapy. [3, 4]
When a change in leg strength needs a closer look
Pain can make a leg feel harder to use. I look at what you can do, how it compares with the other side, and what has changed. If your foot has started catching or you’re losing strength in one leg, contact a medical clinician today. A strength and nerve check helps clarify what’s going on. [11]
Go to the emergency department if you develop new numbness around your genitals or anus, new trouble starting urination or controlling your bladder or bowels, new sciatica in both legs, or severe or worsening weakness or numbness in both legs. [5]
Frequently asked questions
Why do my toes tingle when I stretch my hamstring?
Show me which toes and where the feeling starts. I’d compare what happens as we change the leg or trunk position, then use that alongside the rest of the exam. A stretch that brings on tingling gives us a clue about what to check.
My back feels better, but my foot still tingles. What should we count as progress?
I’d track those separately. Tell me where the tingling ends, how long it lasts after a familiar activity, and what the activity is like now. That helps us decide whether the leg symptoms are changing along with the back.
Why is sitting in the passenger seat harder than walking around the block?
I’d ask how soon the leg symptoms start in each setting and what you need to do to settle them. If a seated position in the clinic brings on the same feeling, we can compare it with a different amount of support.
What if the tingling only shows up after I’ve been driving a while?
We can start with your usual drive as the reference point. Tell me when it starts, how far it travels, and how it changes when you get out. Those details can help guide the exam even if you feel fine when you arrive.
Can I have sciatica without much back pain?
Yes. Leg symptoms can be more noticeable than back pain. Other conditions can also cause leg pain or tingling, so the full pattern and exam matter.
Should I keep stretching through tingling?
Avoid repeatedly pushing a stretch that sends tingling farther down your leg or leaves symptoms worse afterward. Bring that example to an assessment so we can work out what you are feeling and find a tolerable way to move.
Do I need an MRI for sciatica?
An MRI is generally considered when there are concerning findings or the result would change treatment. Your clinician can use your history and exam to help decide. [6, 7, 8]
Does every case need nerve glides?
Nerve glides are movements that gently change how a nerve moves relative to nearby tissues. They are one option for selected people. The exam and your response help determine whether they belong in your plan. Evidence suggests possible short-term benefits for some people with leg pain related to a nerve root in the lower back. [9, 10]
How will we know whether treatment is helping?
First I want to hear what worries you and exactly where the symptoms travel. During treatment we might repeat a short walk or a sit-to-stand and check what happens in your leg. If symptoms spread farther down or linger, I can adjust what we’re doing before we continue.
My MRI shows a disc problem. Is physical therapy still an option?
It can be. Disc changes also show up on some scans of people without pain. I look at how the scan fits your symptoms, strength, and movement. I’ve worked with people who made progress with physical therapy after surgery had come up as an option. If your surgeon has recommended an operation, ask what the timing depends on and whether a trial of physical therapy is appropriate for you. [12]
