"What Happens at the Hospital?" — From Examination to Diagnosis
"What will they do to me at the hospital?" This week answers that question.
Last week, we talked about the typical symptoms of spinal stenosis and when to see a doctor. This week, I'll go through what happens when you visit the hospital, from your first appointment through testing.
Which Doctor Should I See?
"My legs hurt." "My back aches." With symptoms like these, you may wonder which type of doctor to see.
The answer is an orthopedic surgeon.
You can start with your primary care doctor or general practitioner, but the diagnosis and treatment of spinal stenosis falls under orthopedic surgery. You don't need a referral to be seen.
An orthopedic practice that specializes in spine conditions is even better if there is one near you. Spine specialists have the most experience with this condition.
Step 1: The Medical Interview — Tell Us About Your Symptoms
The first thing your doctor will do is ask you detailed questions about your symptoms. Common questions include:
- When did your symptoms start?
- Where does it hurt? Where do you feel numbness?
- What makes it worse? (Walking? Standing?)
- Does resting help?
- How far (or how long) can you walk without stopping?
- Are you having any bladder or bowel problems?
- What treatments have you tried so far?
If you've been keeping the walking distance log from last week, bring it now.
Tips for Your Visit
- Don't hold back; describe exactly what's bothering you
- No question is too small or too silly to ask
- Bringing written notes can help you remember everything
- A family member who comes with you may notice things you miss
Step 2: The Physical Examination — Let Us Check Your Body
After the interview, the doctor will examine you physically.
What the Doctor Checks
| Examination | What They're Looking For |
|---|---|
| Watching you walk | Balance, how well your feet lift |
| Sensation testing | Touch sensitivity, temperature differences between sides |
| Strength testing | Ability to lift the ankle, stand on tiptoes |
| Reflex testing | Tapping the knee and Achilles tendon with a small hammer |
| Range of motion | Pain changes when bending forward vs. backward |
| SLR test | Raising each leg while lying on your back to check nerve tension |
Very little of this is painful. It mostly involves gentle touch and checking how your legs move. Wearing loose, comfortable clothing will make the examination easier.
Step 3: Imaging — Let's Look Inside
If the physical examination suggests spinal stenosis, imaging tests will be ordered.
X-Ray
This is almost always the first test.
- What it shows: Bone changes, disc narrowing, presence of spondylolisthesis
- Duration: About 5 minutes
- Pain: None (you simply stand still for the images)
X-rays cannot show the nerves themselves. They give a general view of the bones.
MRI (Magnetic Resonance Imaging)
This is the most important test for diagnosing spinal stenosis.
- What it shows: How narrow the canal is, the degree of nerve compression, the condition of discs and ligaments
- Duration: 20 to 30 minutes
- Pain: Absolutely none
The name "MRI" can make some people anxious, but in this test you simply lie still, with no needles and no medication.
A few things to know ahead of time:
- It's loud: You'll hear banging and clanking sounds from the machine. Most hospitals provide headphones or earplugs
- It's a tight space: You'll be inside a tube-shaped machine. If you have claustrophobia, let the staff know in advance; some facilities have open MRI machines
- You need to stay still: For 20 to 30 minutes, try to keep as still as possible
- No metal allowed: Remove all jewelry, watches, dentures, and magnetic cards. If you have a pacemaker, be sure to tell the staff beforehand
CT Scan (Computed Tomography)
A CT scan may be added when more detailed bone imaging is needed.
- Provides more detailed bone images than X-rays
- Takes about 5 to 10 minutes
- Often used when planning surgery
Understanding Your Results
When the doctor shows you the MRI images, you'll be able to see where the spinal canal has become narrow.
The doctor will usually point at the images and explain:
"This white area here is the nerve. Can you see how it's being squeezed right at this point?"
Don't hesitate to ask questions. "Could you show me that again?" or "Could I get a copy of my MRI images?" are perfectly reasonable requests.
An Important Point: Images Don't Always Match Symptoms
I mentioned this last week, and it is worth repeating:
Even if the MRI shows a narrow canal, if your symptoms are mild, surgery is usually not the immediate recommendation.
On the other hand, if your symptoms are significant even though the images don't look too severe, more active treatment may be considered.
Images are only one part of the picture. Your treatment plan also takes into account your symptoms, how they affect your daily life, and how you've responded to treatment so far.
What Happens After Your First Visit
After the first examination and tests, the doctor can usually make a general diagnosis. What comes next depends on the severity of your symptoms.
| Severity | Typical Next Steps |
|---|---|
| Mild | Start with medication and rehabilitation (conservative treatment) |
| Moderate | Begin conservative treatment while scheduling regular follow-ups |
| Severe (bladder problems, rapid muscle weakness) | Additional tests and discussion about surgery |
Most people start with conservative (non-surgical) treatment. We'll cover the details of conservative treatment next week.
Key Takeaways
- See an orthopedic surgeon (ideally a spine specialist)
- The typical process: medical interview, physical exam, then imaging (X-ray + MRI)
- MRI is a painless test that lets the doctor see the nerves directly
- Imaging alone doesn't determine treatment; your symptoms and overall picture matter
- Don't hesitate to ask questions at your first visit. Bringing notes or a family member helps
