NECK PAIN · FRONTENAC
Numb hands at night, a carpal tunnel diagnosis, surgery that helped for a while. The wrist was probably only half the problem.
Getting here from Frontenac
Lindbergh north to I-170, then the Natural Bridge exit — around twenty-one minutes. Ground-floor entrance, parking outside.
Where the numbness is actually coming from
A nerve running from the neck to the hand can be compressed at several points along its course, and compression at one point makes it more vulnerable at every other. That is not a theory; it is a well-described phenomenon and it explains a large share of incomplete results after carpal tunnel surgery.
So a patient with genuine carpal tunnel findings can also have a cervical contribution, and releasing the wrist relieves part of the picture while leaving the rest. The symptoms improve, then plateau, and the patient is told the surgery worked and something else must be going on.
Double crush syndrome covers the mechanism, and carpal tunnel or neck covers how the two are separated before anyone operates.
The distribution tells you a lot
Carpal tunnel affects the thumb, index, middle and half the ring finger, and it spares the little finger. Numbness that includes the little finger is not carpal tunnel — it is the ulnar nerve, at the elbow or from the neck.
Symptoms that involve the whole hand, or that come with neck or shoulder blade pain, point upstream. Hand symptoms maps which pattern indicates what, and it is worth reading before accepting a single-site diagnosis.
Night symptoms are not diagnostic on their own
Waking with numb hands is treated as the signature of carpal tunnel, and it is also produced by sleeping positions that close down the neck or stretch the ulnar nerve at the elbow.
The position you wake in matters more than the fact of waking. That is a history question and it is frequently not asked.
Surgery, and when it is right
Where there is progressive weakness, or a clear structural compression matching the examination, surgery is the correct answer and delaying it is not conservative care.
Where symptoms are sensory and fluctuating, the case is much weaker. The distinction is made on examination rather than on the scan.
What to do while you wait
Avoid the positions that reproduce it, keep moving within comfort, and do not sleep with the arm overhead — that position stretches the nerve for hours and is a common overnight aggravator.
Splinting the wrist at night is reasonable and it will not help if the dominant source is the neck, which is itself diagnostically useful.
What not to do with a suspected trapped nerve
Aggressive stretching into symptoms, repeated end-range rotation, and heavy overhead loading all tend to make radicular symptoms worse rather than better.
What not to do covers the common self-management mistakes, most of which are well-intentioned.
What testing actually establishes
Nerve conduction studies and EMG localize the problem rather than confirm a suspicion, and they can identify more than one site at once, which is precisely the situation being missed.
They have limits: they are less sensitive early, and a normal study does not exclude a cervical source. Interpreted alongside examination they are the most useful test available here; interpreted alone they mislead.
When the neck is the dominant source
Cervical radiculopathy produces symptoms in a defined territory with, sometimes, weakness in specific muscles. It responds to different treatment from a wrist problem, and it does not respond to a wrist operation at all.
Cervical radiculopathy covers the presentation, and which root produces what covers the mapping we use on examination.
What we do before recommending anything
Examine the neck, the elbow and the wrist in the same appointment rather than referring you around to have each looked at separately. That is the whole point of assessing this properly: the sites interact and looking at one in isolation is how the picture gets missed.
Only then does the question of treatment arise, and it may well be that the wrist genuinely is the dominant problem — in which case we say so.
Is it permanent?
That is the question people actually want answered. Numbness that has been present for a long time recovers less reliably than recent symptoms, and weakness is a more concerning sign than numbness.
Whether the numbness is permanent gives the honest ranges rather than reassurance.
The symptoms that come from below the neck
One pattern sits outside the usual root-versus-entrapment question and is missed because it belongs to neither category cleanly.
Thoracic outlet syndrome involves compression of the brachial plexus, and sometimes the subclavian vessels, in the space between the collarbone, the first rib and the scalene muscles. The neurogenic form produces symptoms along the inner forearm and into the ring and little fingers — the lower plexus territory — often with aching in the shoulder girdle and symptoms provoked by working with the arms overhead or carrying a bag on that shoulder.
It is over-diagnosed by some and dismissed as nonexistent by others, and neither position survives contact with the patients who have it. The honest description is that the true neurogenic form is uncommon, it is a clinical diagnosis with imperfect confirmatory testing, and it should be considered after cervical and peripheral causes have been properly examined rather than instead of them.
The reason to keep it on the list is that the treatment is different: first-rib and scalene mechanics, posture of the shoulder girdle, and specific rehabilitation rather than anything directed at the neck.
What Frontenac patients ask
I had carpal tunnel surgery and it only half worked. Why?
Frequently because there was a second site of compression, commonly the neck. Releasing one leaves the other: double crush syndrome.
My little finger is numb too. Does that fit carpal tunnel?
No. Carpal tunnel spares the little finger, so that pattern points to the ulnar nerve or the neck: the distribution map.
Do I need nerve conduction studies?
Often, and they localize rather than merely confirm — which is what makes them useful when more than one site is involved: what they show.
How far is it from Frontenac?
About twenty-one minutes via Lindbergh and I-170.
