Elbow Pain That Won't Go Away? Why Rest Alone Won't Fix It
Quick answer: Persistent elbow pain - usually tennis elbow (lateral epicondylalgia) or golfer's elbow (medial epicondylalgia) - keeps coming back because rest doesn't rebuild tendon strength. Once the pain settles and you return to normal activity, the same demand meets the same weakened tendon. The only lasting fix is a progressive loading programme that restores the tendon's capacity to handle the demands of your daily life and sport.
What causes elbow pain that won't go away?
Persistent elbow pain of this type is almost always a tendinopathy - a degenerative change in the tendons attaching at either the outer (lateral) or inner (medial) side of the elbow. Tennis elbow (lateral epicondylalgia) affects the tendons of the forearm extensor muscles on the outer elbow and is the most common. Golfer's elbow (medial epicondylalgia) affects the flexor tendons on the inner side. Both are caused by repetitive loading - from sport, manual work, gym training, or even prolonged keyboard and mouse use - that exceeds the tendon's current capacity.
Why does resting your elbow not fix elbow tendon pain?
Tendons behave very differently from muscles when injured. A muscle strain heals primarily through rest. A tendon problem involves structural changes - disorganisation of collagen fibres - that are not reversed by rest alone. Rest removes the painful trigger, but the tendon remains structurally compromised. The moment you return to the same grip, lift, or sport, the same demand meets the same impaired tendon and the pain returns. This is the cycle that keeps elbow pain going for months and sometimes years. The tendon needs controlled, progressive loading to stimulate the structural repair process.
What does physio for elbow pain actually involve?
At Sports Physio Ireland, elbow tendinopathy rehabilitation is built around a structured loading programme. Your physiotherapist will start by identifying the aggravating activities and your current pain threshold, then introduce controlled isometric (static) exercises to begin tendon loading with minimal pain. As tolerance improves, you progress to isotonic and then heavy slow resistance exercises, gradually increasing load over 8 to 12 weeks. Alongside this, manual therapy for elbow and wrist joint mobility, grip strengthening, and advice on modifying provocative activities all form part of treatment. The goal is not just pain relief - it is restoring the tendon to full functional capacity.
How long does elbow tendon pain take to get better?
With the right rehabilitation, most people see meaningful improvement in tennis or golfer's elbow within 6 to 8 weeks. Full resolution - where you can grip, lift, and use your arm without thinking about it - typically takes 3 to 4 months of progressive loading. Elbow tendinopathy that has been present for over a year (chronic tendinopathy) may take 4 to 6 months. The key variable is consistency with the loading programme: patients who follow the programme closely tend to recover significantly faster.
Understanding Why Elbow Pain Keeps Coming Back
Elbow pain has a pattern. It starts small. Then it lingers.
Then it becomes part of everything you do.
WHY IT FEELS DIFFERENT
Unlike muscle pain, this doesn’t “warm up.”
It stays.
Sometimes worse after activity.
Sometimes worse the next day.
That’s because:
👉 Tendons react differently to stress
It rarely starts as a problem.
More like… a niggle.
You feel it when you grip something tightly.
Maybe when you lift a weight.
Or after a game, when everything settles and you notice it more.
And for a while, that works.
Until it doesn’t.
WHEN IT STOPS BEING IGNORABLE
What used to be “just a bit sore” starts showing up more often.
Now it’s:
Picking up a kettle
Carrying shopping bags
Opening a jar
Simple things.
Things you don’t think about… until they hurt.
And that’s usually the moment it shifts from:
👉 “This is annoying”
to
👉 “Why is this still here?”
THE PART THAT CONFUSES MOST PEOPLE
Because you probably tried the obvious things.
You rested it.
You avoided the movements that hurt.
Maybe you even took a break from training or sport.
And it did improve.
But the second you went back?
👉 It came straight back with you
That’s the frustrating part.
It feels like it’s healing…
But never actually gets better.
WHAT’S ACTUALLY GOING ON
This isn’t just a sore muscle.
It’s a tendon problem.
And tendons behave differently.
They don’t respond well to being completely rested.
But they also don’t tolerate being overloaded suddenly either.
They sit somewhere in between.
And when they’re not handled properly, they become:
👉 Sensitive to the exact things you do every day
Gripping.
Lifting.
Repetitive use.
So instead of improving, they stay stuck in this cycle of:
Use → Pain → Rest → Repeat
WHY “JUST REST IT” DOESN’T WORK
Rest removes the trigger.
But it doesn’t change the tendon.
So when you go back to normal activity…
👉 The same demand meets the same capacity
And the same pain returns.
That’s why this kind of elbow pain can last for months.
Not because it’s severe.
But because it’s never properly rebuilt.
WHERE MOST PEOPLE GO WRONG
It’s usually one of two things:
They either:
Avoid using it too much for too long
Or
Jump straight back into full activity once it “feels okay”
Both seem logical.
But both keep the problem going.
Because neither approach actually prepares the tendon for what you need it to do.
WHAT A PROPER FIX LOOKS LIKE
This is where physio changes the direction completely.
Instead of avoiding the problem…
We start rebuilding the tendon’s ability to handle load.
Gradually. Specifically. Properly.
That usually involves:
Introducing controlled loading that the tendon can tolerate
Progressively increasing strength through the forearm and elbow
Reintroducing real-world movements in a structured way
Not randomly.
Not aggressively.
But with a clear progression.
THE TURNING POINT
There’s usually a moment where things start to shift.
Not overnight.
But noticeably.
Where:
Pain becomes less reactive
Strength starts to return
Everyday tasks stop triggering it
And most importantly:
👉 You stop thinking about your elbow all the time
THE PART PEOPLE DON’T EXPECT
Fixing this isn’t just about getting rid of pain.
It’s about restoring trust in your arm again.
Because once something has been sore for long enough…
You start to protect it without realising.
You grip differently.
Lift differently.
Move differently.
And that can keep things going even longer.
FINAL THOUGHT
If your elbow pain keeps coming back…It’s not because it’s “just one of those things.” And it’s not something you have to live with. It just hasn’t been guided properly yet.
