When should I go to the ER for knee pain?

Go to the ER if you can't put any weight on the leg after an injury, the knee or kneecap looks deformed or out of place, the joint is hot, red and swollen with a fever, the knee is locked and won't straighten, or your foot below the injury is numb, cold or pale. Call 911 if calf swelling comes with chest pain or breathlessness, which can mean a blood clot has travelled to the lungs.

Can physiotherapy help knee pain?

Yes, for most common causes. Exercise-based physiotherapy is a first-line treatment for patellofemoral pain, tendinopathy and knee osteoarthritis, and it is central to recovery after ligament and meniscus injuries, whether or not surgery is needed. A physiotherapist assesses what is driving the pain, then builds a progressive strengthening and movement programme around your goals.

Do I need a doctor's referral to see a physiotherapist in Amman?

Not at Emergency Plus. You can book a physiotherapy assessment directly, without a referral. The clinic in Dabouq is open 9:00 to 20:00 daily. If the physiotherapist finds anything that needs a doctor or an X-ray, the emergency department and urgent care are in the same building.

How do I know if my knee pain is serious?

Warning signs are a pop with rapid swelling after a twist, the knee giving way, being unable to bear weight, a knee that locks, a hot swollen joint with fever, pain that wakes you at night and doesn't ease with changing position, or calf pain and swelling. Pain that steadily improves over a few days with sensible activity is usually not serious.

Should I rest my knee or keep moving?

For a few days after a strain, ease off whatever makes it worse, but avoid complete bed rest. Gentle movement and walking within comfort help most knee problems recover. For longer-standing pain such as patellofemoral pain or osteoarthritis, the right kind of exercise is part of the treatment, not something to avoid.

Is it a torn meniscus or a ligament injury?

It is hard to tell without an examination. Ligament injuries such as an ACL tear often follow a sudden change of direction with a pop, swelling within a few hours and a feeling of the knee giving way. Meniscus tears often follow a twist under load, with pain along the joint line, swelling over a day or so, and catching or locking. Both need assessment.

Knee Pain: Physiotherapy or the ER? How to Tell

Maybe it started after a Friday football match, or a week of climbing Amman's stairs, or for no obvious reason at all. Your knee hurts going downstairs, getting up from a chair, or kneeling for prayer. And the question going round your head: is this something that will pass, does it need an X-ray, or is it physiotherapy? The good news is that most knee pain isn't serious and responds well to the right treatment. What matters is knowing the few signs that mean it can't wait.

When is knee pain an emergency?

Go to an emergency department — or call 911 where stated — in these situations:

You can't put weight on the leg after a fall, blow or twist — it may be a fracture and needs an X-ray.
Obvious deformity, a kneecap that has popped out of place, or a knee that looks "wrong".
A numb, cold, pale or bluish foot after a major knee injury — call 911; blood vessels may be damaged.
A hot, red, swollen knee with fever, chills or feeling unwell — this can be a joint infection, which damages the joint quickly if treatment is delayed.
A locked knee you can't fully straighten after a twist — a torn piece of cartilage may be caught in the joint.
Calf pain and swelling with warmth or redness, especially after surgery, a long journey or a period of immobility — possible deep vein thrombosis. If it comes with sudden chest pain or breathlessness, call 911.

If you're not sure whether your injury is a break or a sprain, our guide on telling a broken bone from a sprain will help. At Emergency Plus, the emergency department is open 24/7 with on-site X-ray, ultrasound and laboratory.

Common causes of knee pain

Patellofemoral pain ("runner's knee")

A vague ache around or behind the kneecap, worse going downstairs, squatting, kneeling and sitting for long periods with the knee bent. Very common in teenagers, runners and anyone who has suddenly increased their activity. It usually doesn't mean joint damage, and responds well to thigh and hip strengthening and adjusting load.

Ligament and meniscus injuries

The ACL is usually injured with a sudden change of direction or an awkward landing — especially in football and basketball — with a pop, rapid swelling within hours and a sense of the knee giving way. The MCL is often injured by a blow to the outside of the knee. The meniscus tears when the knee twists under load, or gradually with age, causing pain along the joint line, swelling over a day or so and sometimes catching or locking. These injuries need assessment first, then structured rehabilitation, whether or not surgery is needed.

Osteoarthritis

Activity-related pain and brief stiffness after rest, developing over months or years, and more common after 45. X-ray findings don't always match how much it hurts, and UK NICE guidance puts therapeutic exercise and weight management at the core of treatment. Many people assume arthritis means they should stop moving; the opposite is true — stronger muscles protect the joint.

Tendinopathy

Localised pain just below the kneecap (patellar tendon, or "jumper's knee") or just above it (quadriceps tendon), brought on by jumping, running and squatting, and often worst at the start of activity. Complete rest rarely fixes it; gradually loading the tendon with well-chosen exercise does.

Knee pain in children and teenagers

Teenage athletes going through a growth spurt often complain of pain and a tender bump just below the kneecap that's worse with running and jumping — usually irritation where the tendon attaches to growing bone (Osgood-Schlatter disease), which generally settles with adjusted activity and the right exercises. But one point matters: in children, knee pain can actually be coming from the hip. A child who is limping or refusing to walk, has knee pain with a fever, pain that wakes them at night, or swelling with no clear injury needs a medical assessment the same day — not physiotherapy first.

Knee pain after surgery or a long journey

After knee or hip surgery, a long flight or drive, or a spell confined to bed, the risk of deep vein thrombosis rises. Pain and swelling in the calf — rather than the knee itself — with warmth and redness deserves an urgent same-day assessment. The expected pain and stiffness after surgery, on the other hand, improve with a structured rehabilitation programme; see our guide to physiotherapy after surgery.

Where to go: a quick guide

Pattern	Likely cause	Where to go
Ache around or behind the kneecap, worse on stairs, squatting or after sitting	Patellofemoral pain	Physiotherapy
Pain just below the kneecap with jumping, running or kneeling	Patellar tendinopathy	Physiotherapy
Stiff, achy knee over months, often age 45+, worse after activity	Osteoarthritis	Physiotherapy (doctor review if unsure)
Twist or pop in sport, swelling within hours, knee gives way	Ligament (e.g. ACL) or meniscus injury	Urgent care for assessment, then physiotherapy
Can't put weight on it after a fall or blow, or the knee looks deformed	Possible fracture or dislocation	Emergency department
Hot, red, swollen knee with fever or feeling unwell	Possible joint infection	Emergency department, same day

Will knee pain go away on its own?

Many minor strains improve within days to a few weeks with a short period of easing off, then a gradual return to activity. But pain that comes back every time you return to running or sport, or a knee that gives way, rarely resolves with waiting alone: muscles weaken as you avoid movement, the joint becomes less protected, and you end up in a cycle of pain, rest, weakness and pain again. Breaking that cycle is exactly what physiotherapy is good at.

When should you see a physiotherapist for knee pain?

Pain lasting more than two weeks, or returning every time you go back to activity.
Pain stopping you from managing stairs, sport or prayer comfortably.
A knee that gives way or feels unstable.
After a ligament or meniscus injury has been assessed, to rebuild strength and confidence.
Arthritis stiffness and pain limiting your walking and daily life.
Before and after knee surgery.

What does physiotherapy for knee pain involve?

Assessment: the story of your pain and how it started, then a look at movement, strength, stability, how you walk and squat, and tests for ligaments and cartilage. If anything suggests you need imaging or a doctor, we'll point you there.
Explanation: what is most likely causing the pain, what to expect, and what you can do or should ease off for now.
A progressive exercise programme: strengthening for the thigh, hip and calf, plus balance and control work, made harder as you improve.
Load management: how to adjust running, sport or work rather than stopping completely.
Return to activity: clear milestones for getting back to sport or daily life with confidence.

At the Emergency Plus physiotherapy clinic in Amman in Dabouq, you can book directly with no referral, and the clinic is open 9:00–20:00 daily. If you're an athlete aiming to get back on the pitch, our guide to returning to sport after injury explains the stages.

What you can do at home for knee pain

For a few days, ease off whatever aggravates it (running, jumping, deep squats), but keep walking within comfort.
After a fresh injury: ice wrapped in a towel for up to 20 minutes every two to three hours, raise the leg, and use light compression if it helps.
Pharmacy painkillers such as paracetamol, or anti-inflammatories like ibuprofen if they're suitable for you — ask the pharmacist, especially if you have stomach or kidney problems or take blood thinners.
Avoid complete bed rest; the knee stiffens and weakens quickly.
If praying on the floor hurts, praying on a chair for now is a reasonable option while it settles.
If the pain hasn't improved in two weeks, or is getting worse, it's time for an assessment.

If an injury is fresh and needs checking today but doesn't look like an emergency — swelling after a twist while you can still walk, for example — urgent care sees walk-ins around the clock, with on-site X-ray.
