A joint hurts. The muscle around it won't contract properly. You've been given exercises, and doing them either aggravates the pain or produces nothing at all. So you're stuck between two instructions that seem to contradict each other: rest it, and strengthen it.
The contradiction disappears once you know the order. These are three separate stages, and each one only works when the stage before it has been dealt with.
Why the order matters

Pain, activation, and strength are three different problems, and they sit in a fixed sequence.
Pain suppresses activation. That's a protective reflex, not a choice, and while it's running the muscle can't be recruited properly no matter how much effort goes in. Activation, in turn, is what makes loading productive. A muscle you can't fully contract can't be loaded properly, and trying anyway usually just irritates the joint further.
Which means starting at the wrong end wastes the work. Loading a muscle you can't activate is slow and often counterproductive. Trying to restore activation while the pain is still driving the inhibition is working against a live signal. Most stalled recoveries are correctly ordered work that started at step three.
The sequence runs in one direction. Settle the pain. Restore the activation. Then load it.
Step one: settle the pain

The first job is reducing the pain input, because that's what's suppressing the activation. This isn't about masking anything. It's about removing the signal that's keeping the muscle switched down.
Practically, this means reducing the aggravating load for a period rather than stopping altogether, since complete rest brings its own deconditioning cost. It also means addressing the pain signal directly.
Transcutaneous Electrical Nerve Stimulation is one of the established tools for this, and it works through Gate Control Theory. Sensory nerves and pain-carrying nerves share pathways into the spinal cord, so introducing a competing sensory signal occupies that pathway and reduces how much pain input reaches the brain.
The Vibit Pulse delivers this at home through EasyStick pads applied at the pain site, with four modes and ten intensity levels so the stimulation can be matched to the area. It's the same technology physios use, without the appointment.
What you're looking for at the end of this stage is not zero pain. It's enough reduction that movement becomes tolerable and the muscle starts responding again when you ask it to.
Step two: restore the activation

Once the pain has settled, the question becomes whether the muscle actually fires properly. For a lot of people it comes back on its own at this point. For others it doesn't, and that's the stage most commonly skipped.
The test is simple enough to do yourself. Contract the muscle on the affected side as hard as you can, then do the same on the other side and compare. If one side feels noticeably weaker, delayed, or as though part of it isn't participating, activation hasn't fully returned.
Restoring it is different work from strengthening. It's low load, high focus, and deliberately unimpressive: isolating the muscle, holding a contraction, paying close attention to whether it's actually engaging rather than to how much weight is moving. Clinically this is where a physiotherapist earns their place, and where Electrical Muscle Stimulation is used when voluntary activation stays stubbornly suppressed.
Skipping this stage is the single most common reason strength work stalls. You can't strengthen what you can't recruit.
Step three: load it progressively

Only once the muscle activates properly does loading do what it's supposed to do.
Progressive means adding load gradually enough that the tissue adapts rather than protests. The useful marker isn't how the session feels at the time, it's how the joint feels the following morning. Some fatigue is fine and expected. A return of the original pain means the jump was too large, and the answer is to step back rather than push through.
This is also the longest stage by a considerable margin. Settling pain can take days to a few weeks. Restoring activation is often a similar span. Rebuilding strength that took months to lose takes months to recover, and expecting otherwise is how people conclude that something isn't working when it's simply not finished.
When the sequence resets

Flare-ups happen, and when they do the sequence resets rather than continues.
A significant increase in pain reintroduces the inhibition, which means loading is no longer productive until the pain has settled again. Dropping back to step one for a period isn't losing ground. Pushing through a flare-up with the same load is what actually costs you time.
Progress in this kind of recovery tends to look like a series of steps forward with occasional steps back, not a straight line. That pattern is normal and doesn't indicate the approach is failing.
When to get it looked at

This sequence assumes a known, diagnosed problem that you're working through. It doesn't replace assessment, and some things need to be looked at rather than worked around.
See a physiotherapist or doctor if the joint gives way or locks, if there's significant swelling that isn't settling, if the pain wakes you at night consistently, if there's numbness or pins and needles, or if you have no clear explanation for the pain in the first place. Persistent weakness that hasn't shifted at all after several weeks of appropriate work is also worth raising specifically as a question about activation rather than strength.
A clinician can tell you which stage you're actually at, which is genuinely difficult to judge from the inside.
The short version

Settle the pain enough that the muscle will respond. Confirm the muscle actually fires before you start loading it. Then load it slowly, and judge each increase by how the joint feels the next day rather than during the session.
Most of the time the work wasn't wrong. The order was.
