"Signs of Worsening" — Changes You Should Not Ignore

"Being able to tolerate it" and "it's not getting worse" are not the same thing.

Last week, we discussed the types and benefits of conservative treatment. While many people do improve with conservative care, one of the hardest questions is: "How long should I keep going with it?"

This week, I want to talk about the warning signs you should not ignore while continuing conservative treatment.

It's Hard to Notice Because It Happens So Slowly

In most cases, spinal stenosis doesn't worsen suddenly. It progresses gradually, over months and years.

And that's exactly what makes it tricky.

When the distance you can walk gets a little shorter each month, you unconsciously adapt. You start going to the nearby convenience store instead of the supermarket that's farther away. Your walks get shorter. You go out less often. Before you know it, your life has changed significantly — without you ever noticing a single dramatic shift.

Take a moment and think back: what were you doing easily a year ago that has now become difficult?

Five Warning Signs to Watch For

If you notice any of the following changes, it's time to talk to your doctor again.

Sign 1: Decreasing Walking Distance

This is the clearest indicator.

The walking distance log we recommended in Week 3 becomes invaluable here. Having real numbers — not just feelings — makes it easier for both you and your doctor to track changes.

Sign 2: Loss of Leg Strength

• Tripping more easily (difficulty lifting the foot)
• Slippers or sandals slipping off your feet
• Stairs becoming harder (needing to grip the handrail)
• A general feeling of weakness in your legs

Muscle weakness is a sign that nerve compression is worsening. If the weakness develops quickly over a short period, it's especially concerning.

Sign 3: Spreading Numbness

If the area affected by numbness is expanding, pay close attention.

• It started in your buttocks and has now reached your thighs
• It used to stop at your calves but now extends to the soles of your feet
• It was on one side but has now appeared in both legs

When numbness spreads, it may mean that more nerves are being compressed.

Sign 4: Bladder or Bowel Changes

I mentioned this last week, but it's important enough to emphasize again.

• Difficulty starting to urinate
• Not making it to the bathroom in time
• A feeling of incomplete emptying
• Worsening constipation
• Unusual sensation around the anal area

These symptoms are a sign of severe compression of the cauda equina nerves. See your doctor immediately. Delay can make recovery much more difficult.

Sign 5: Shrinking Daily Life

This one is harder to measure with numbers, but the impact on your daily life is a crucial piece of the picture.

Are any of these becoming more common?

• Feeling reluctant to go shopping
• Turning down invitations from friends
• Finding it too painful to play with grandchildren
• Giving up on travel plans
• Dropping hobbies you once enjoyed — golf, gardening, community activities

"I can't do the things I want to do anymore" — that's a sign that your condition is encroaching on your life.

The "I Can Still Walk, So I'm Fine" Trap

One of the most common things I hear in my clinic is this:

"I can still walk, so I'm fine."

I completely understand that feeling. "I can still walk = I'm still okay" seems logical.

But as a doctor, I have to be honest — "still being able to walk" and "being in the best possible condition" are not the same thing.

Here's why: when nerves are compressed for a long time, they may not fully recover even after the compression is removed.

Numbness, in particular, is a symptom that becomes stubbornly persistent once it sets in. Even after surgery successfully relieves nerve compression, numbness that has been present for years may not completely go away.

In other words, the earlier you seek treatment, the better your chances of recovery.

Waiting until you "can't walk at all" may mean the nerves have already sustained damage that can't be undone.

"I Can Tolerate It" Is Not the Right Yardstick

In many cultures, there's a tradition of enduring pain stoically. "I can handle this." "Other people have it worse." These are common reasons people give for putting off treatment.

But "whether you can tolerate it" is not the right measure of whether you should seek treatment.

The right questions are:

• Are your symptoms getting worse, or are they stable?
• Is your daily life being limited?
• Is conservative treatment actually helping, or not?

Checking in on these questions regularly with your doctor is what truly matters.

When to See Your Doctor

If any of the following apply to you, I recommend contacting your doctor without waiting for your next scheduled appointment.

• Your walking distance has clearly decreased compared to three months ago
• Your legs are getting weaker (tripping, slippers falling off)
• Numbness is spreading to new areas
• You've noticed changes in bladder or bowel function
• Activities you used to do easily have become difficult or impossible

If even one of these applies, please let your doctor know.

Key Takeaways

• Spinal stenosis progresses slowly, making worsening easy to overlook
• Decreased walking distance, muscle weakness, spreading numbness, bladder changes, and lifestyle limitations are five warning signs
• "I can still walk" and "I can still tolerate it" are not reliable measures
• Nerves that are compressed for too long become harder to heal — acting sooner leads to better outcomes
• Check in regularly with your doctor, and reach out promptly if you notice changes
