Recovery after spinal surgery

The surgery sorted out the structure. What is left is getting the confidence back.

It is common to leave the operating theatre with the anatomical problem dealt with and still not know what you can do, how far you can go, or why it still hurts.

Nobody usually explains that part. And it is that part that decides whether you get back the life you had.

Do you recognise yourself in any of these?
You had the surgery and the pain did not go away as you expected
You no longer have severe pain, but you avoid bending or lifting
You lost strength or muscle during the recovery
Nobody explained clearly how far you can go
You want to train, garden or pick up your grandchildren again
You feel that "the surgery did not work" and left it at that

Recognising yourself in one is enough. They are different situations, with different routes.

First of all

Surgery should be the last of the options. Sometimes it really is the right one.

For the overwhelming majority of spinal problems, the literature recommends starting with conservative treatment — often before imaging and medication. Only a handful of very specific situations fall outside that rule.

But there are cases where there is no alternative: the situation really is surgical, or conservative treatment was tried and could not help. In those cases surgery is indicated, and it is the right decision.

If you have already had surgery, this is not a judgement on your decision. It is the opposite: it is the reason why what comes after surgery deserves as much care as the surgery itself.

There are two very different situations behind the same sentence

"I had spinal surgery and I am not well" can mean two almost opposite things. Confusing them leads to treating the wrong person the wrong way.

Situation 1
The pain carries on

Months have passed and the pain has not gone away as you expected, or it changed in character and settled in. This has a name of its own and a classification of its own — it is called chronic post-surgical pain, and it is defined as pain persisting beyond the healing process, at least three months after the operation.

Having a name matters more than it seems: it means it is not in your imagination, it is not a lack of willpower, and it is not necessarily a sign that the surgery went wrong.

Situation 2
The pain went, but the fear stayed

You no longer have severe pain — sometimes a nagging, persistent ache, sometimes none — but you still avoid bending forwards, you do not pick up your grandchild or your child, you put off going back to the gym because you do not feel confident. You lost strength during the months of recovery, and nobody told you clearly how far you can go.

This is, in my experience, the more common of the two — and the one that most often ends up with no treatment at all, because "everything went well" at the follow-up appointment.

I work with whoever operated on you. Not against them.

Every operation has its own restrictions, its own timescales and its own particulars. A spinal fusion is not a microdiscectomy, and what is safe in one case may not be in another.

So I will want to know exactly what was done to you, at which level, how long ago, and what instructions you were given. If there is any relevant doubt about what you can or cannot do at this stage, I tell you to check with your surgeon before we go ahead — I do not guess.

The aim is not to work against the surgery. It is to make the most of it — to give you the physical capacity that the operation, on its own, does not give back.

Frequently asked questions

If yours is not here, ask me directly.

A long time has passed and it still hurts. Did the surgery fail?

Not necessarily, and that conclusion is unfair to you. There is an internationally recognised entity called chronic post-surgical pain — pain persisting beyond healing, at least three months after the operation. It is classified in the ICD-11 precisely because it is common enough to have a place of its own. Having pain does not mean the operation failed to correct what it set out to correct.

Can I use the gym after a spinal fusion?

In many cases yes, with proper progression and adjustments to some movements. But it depends on what was done to you, at which level, and how long ago — and on the instructions your surgical team gave you. I will want to know all of that before answering, and if I am left with any relevant doubt I ask you to check with your surgeon. I do not guess on your behalf.

Do I need my doctor's permission to start physiotherapy?

In Portugal you can go directly to a physiotherapist, without a referral. After an operation, however, I like to know what the surgical report and the instructions you were given say — not out of legal obligation, but because it changes what is safe to do and when.

They are talking about a second operation. What should I make of it?

That the decision is yours and your doctor's, not mine — but that it is worth understanding clearly what it is expected to achieve and what alternatives exist. One thing worth knowing: for low back pain with no identified structural cause, current evidence does not support spinal fusion, and a trial of 349 adults found no advantage of fusion over intensive rehabilitation in functional capacity. That does not apply to every case, but it is a legitimate question to ask whoever is proposing to operate.

Signs that cannot wait for an appointment

Nothing on this page replaces an assessment by a healthcare professional. And there are situations that are not a matter for physiotherapy at all:

this calls for urgent medical care, the same day.

In the spine, generally
Severe pain that does not ease in any position and that gets worse from one day to the next
Loss of sensation that gets worse from one day to the next, in a leg or an arm
Fever, with no known infection to explain it
Unexplained weight loss — around 10% of your body weight in six months, with no diet or exercise to account for it
When it starts in the lower back
These may indicate cauda equina syndrome.
Numbness or altered sensation across the whole area covered by underwear — genitals, perineum and inner thighs
Losing the ability to hold in urine or stools
Or exactly the opposite: no longer being able to pass urine or open your bowels
Loss of strength in a leg, particularly if it is getting worse
When it starts in the neck
These may indicate cervical myelopathy.
A change in the way you walk that came on suddenly — a feeling of walking as if drunk
Suddenly losing strength or sensation and dropping light objects from your hand
Gradually losing movement in the arm from one day to the next
New clumsiness in fine movements: doing up buttons, writing, picking up coins
In these cases there is only one route: the emergency department.

A medical appointment the same day, as soon as possible, with neurosurgery or spinal orthopaedics.

This is not a matter for physiotherapy, nor for any other healthcare professional.

And it is not a matter of waiting to see whether it improves. Here, time is what weighs most on the outcome: the sooner you are seen by a doctor, the better.

See every sign, by area, and what to do in each case

Tell me what was done to you and what you still cannot do.

Which operation, how long ago, and which movement you avoid. With that I can already tell you a good deal, and frankly.

Initial conversation free of charge. I always reply — and, most of the time, the same day.
