Why the Night Tingling Stops in Days but Your Grip Takes Months
Carpal tunnel release cuts the thick ligament forming the roof of the tunnel, so the median nerve finally has room. Ten to fifteen minutes, usually under local anaesthetic, usually walking out the same morning.
The night waking normally stops within a few days. Sometimes the first night.
And that’s where the expectations go wrong, cos people take that fast win as the signal that recovery is basically done…then get blindsided at week 3 by a palm that hurts to lean on and a grip that can’t open a jar.
The nerve gets relief in days. The hand therapy and rehab alone takes 3 to 6 months. Both of those are the operation working normally.
What actually got done in there
The tunnel had bone as its floor and a tough ligament as its roof, with nine tendons and one nerve packed inside and no spare room. The surgery divides that roof. It doesn’t remove anything, and it doesn’t repair the nerve.
The two cut ends of the ligament sit apart and scar together over the following months, longer than they were before. That’s the whole point: a bigger tunnel, permanently.
Which explains everything that follows. You have a divided structure in the palm of your hand knitting back together, and the arch of the hand it used to brace has to re-adapt.
Open technique means a scar in the palm. Endoscopic means smaller cuts and often a slightly faster return to work, but the ligament is divided either way and the deep healing timeline is much the same.
Pillar pain: the thing nobody warned you about
If your palm is tender in the two fleshy mounds either side of the scar, especially when you push up from a chair, do a press-up, carry a tray or lean on the heel of your hand…that’s pillar pain.
It’s extremely common and it’s not a complication.
It typically fades over 3 to 6 months. For a minority it lingers longer. Nobody’s fully settled on the mechanism, but the honest version is that a structure bracing the arch of your hand was divided and the hand takes months to renegotiate load through that area.
I’ve had patients convinced the surgery failed at week 4 purely because of this. It hadn’t. Just that they didn’t know what to expect and didn’t know it was coming.
The nerve part, honestly
This is where your pre-op state decides your outcome, and there’s no negotiating with it.
If you went in with intermittent night tingling and normal daytime sensation, expect close to full recovery.
If you went in with numbness that was constant and a flattened muscle mound at the base of the thumb, the surgery has stopped the compression, but it cannot regrow nerve fibres that already died. Sensation improves over 6 to 18 months as surviving fibres recover and sprout. Some of it may not come back. Thumb strength may not fully return.
The operation stops the squeezing. It does not undo the years of damage and perhaps…nerve death.
Which is the same point I make in the carpal tunnel article, just from the other side of it. Nerve recovery is measured in months and it is measured from wherever you started.
What recovery feels like, week by week
- Days 1 to 5: bulky dressing, hand elevated, fingers moving fully from day one. Night symptoms usually already better. Keep the fingers, elbow and shoulder moving…stiffness starts in the joints nobody operated on.
- Weeks 1 to 2: dressing down, stitches out around day 10 to 14. Light everyday use encouraged: eating, dressing, typing. Desk work back around now for many people.
- Weeks 2 to 6: scar massage and desensitisation start once healed. The scar will be firm, raised and hypersensitive…that’s a normal scar at 3 weeks, not a bad one. Grip is noticeably weak here and often weaker than before surgery. Expected.
- Weeks 6 to 12: grip strength climbing properly. Most manual and heavier work resumes in this window. Pillar pain is usually easing but present.
- Months 3 to 6: grip back to or above pre-op levels for most people. Scar softening and flattening. Pillar pain mostly gone.
- Months 6 to 18: the slow tail of nerve recovery, if you had significant numbness going in.
When to actually be concerned
Most of the alarming-feeling things above are normal. These are not:
- Increasing redness, heat, spreading swelling or discharge from the wound, or a fever: infection, call the surgeon.
- Night symptoms that never improved at all: worth a conversation about whether the compression was truly at the wrist.
- Pain that is escalating rather than settling after week 2, especially with a shiny, colour-changed, sweaty, exquisitely sensitive hand and rapidly worsening stiffness: that pattern needs assessing early, not at the next routine appointment.
- Fingers you can’t fully bend or straighten by week 3: get to a hand therapist. Stiffness caught early is cheap.
The short version
Night tingling: days. Stitches: 2 weeks. Desk work: 1 to 2 weeks. Manual work: 6 to 12 weeks. Grip strength: 3 to 6 months. Scar comfort: 3 to 6 months. Nerve sensation, if it was badly compressed: up to 18 months, and possibly not all of it.
A sore palm at week 4 is not a failed operation. It’s week 4.
