Why an Old Injury Still Hurts Months Later
The scan was clear, the physio discharged you, and the ankle still is not right. So why does an old injury still hurt? When an old injury still hurts months after everything should have healed, people usually assume something was missed. Occasionally that is true. More often, the tissue healed and the system around it never went back to normal.
Why an old injury still hurts
- Guarding that never switched off. Muscles tightened to protect the area during the injury and simply stayed that way
- Reduced movement, because you have been unconsciously avoiding the range that hurt
- Weakness in the muscle around the joint from months of doing less
- Scar tissue and adhesion, where tissue healed less freely than it moved before
- A sensitised area, where the nervous system is still treating ordinary load as a threat
Traditional practice reads a lingering injury as stagnation that never fully cleared. Circulation through the area stayed sluggish, the surrounding tissue stayed tight, and the whole region has been quietly under-used ever since. That is why the pain is often fixed in one spot and why it eases with movement and warmth.
What actually helps
- Treat the guarding, not just the spot. The tight protective muscle around an old injury is usually what limits you now
- Warmth rather than ice. The acute phase is long gone, and heat suits stagnation
- Restore the range you have been avoiding, gradually and deliberately
- Load it again. Strength through the full range is what convinces the area it is safe
- Cupping over thick muscle — back, hamstring, calf — where tightness is the limiting factor
- Keep the area warm in cold weather, since old injuries reliably complain about it
Our guide to the first 72 hours after a sprain covers the other end of the timeline, and cupping marks and what they mean explains what to expect from that side of treatment.
Why an old injury still hurts long after it healed
There is a part of this that rarely gets discussed. When an old injury still hurts, people stop trusting the limb. They avoid the movement that once caused it, favour the other side without noticing, and gradually build a way of moving that protects an area which no longer needs protecting.
That shows up as stiffness elsewhere. A guarded ankle loads the opposite hip. A protected shoulder recruits the neck. So the complaint that brings someone in is frequently not the original injury at all, but what grew around it. The Australian Government’s healthdirect sports injuries guide covers the medical side of recovery.
Therefore treatment usually works on both. Free the area itself, then rebuild enough strength and range that you stop guarding it without having to think about it.
When it is worth re-investigating
Please arrange assessment if the joint locks, gives way or feels unstable; if there is numbness, weakness or pins and needles; if pain is steadily worsening rather than plateaued; if there is swelling that keeps returning; or if pain wakes you at night. Those patterns deserve another look rather than more patience.
Where the structure is sound and the area is simply stuck, our page on acupuncture for sports injuries explains how we approach it.
Frequently asked questions
Why does an old injury still hurt if the scan is clear?
A clear scan rules out structural damage, not the guarding, stiffness and weakness that build up around an injury. Those are the usual culprits and they do not show on imaging.
Is it too late to do anything?
Rarely. Long-standing stiffness can still change once treatment is aimed at the surrounding tissue rather than the original site.
Why does it ache in cold weather?
Old injuries are notoriously weather-sensitive. Cold stiffens tissue and reduces circulation through an area that was already compromised — the same pattern seen with worn joints.
