Knee Pain at Night: Causes and Treatment

ByPrime Star Hours

Do you have trouble sleeping due to knee pain? In this article, we’ll explore the causes and solutions for nighttime knee pain to help you get better sleep.

Nighttime knee pain can disrupt your sleep and overall well-being. Lack of sleep can make pain feel worse, creating a cycle of discomfort.

We’ll provide insights into the causes and remedies for knee pain at night, a common issue for people of all ages. It’s more common in those over 50 due to wear and tear on the knee joint, which is a complex structure involving bones, ligaments, tendons, and cartilage, making it susceptible to injuries and conditions.

Causes of Knee Pain at Night

Knee pain at night can happen for various reasons, not just one. Sometimes, it’s not even due to a medical problem. Instead, it can be caused by things like strenuous exercise, sitting too long, or kneeling for a long time.

Common causes of nighttime knee pain include runner’s knee, osteoarthritis, bursitis, or injuries. Some, like runner’s knee, may get better with rest, while others, like osteoarthritis, are long-lasting.

1. Runner’s Knee

Runner’s knee, also known as patellar tendonitis, is a common problem for athletes that can cause knee pain. If you have runner’s knee, you might feel:

  • A dull ache behind your kneecap.
  • Pain near your knee that spreads.
  • A grinding sensation around your kneecap.

This pain happens when your kneecap doesn’t move correctly, rubbing against the lower thigh bone. Several things can cause runner’s knee, like:

  1. Too Much Training: Doing too much or stressing your knee too often.
  2. Kneecap Not in Place: Sometimes, your kneecap isn’t properly positioned in your knee joint.
  3. Walking or Running Problems: Having an unusual way of walking or running, like feet rolling inward.
  4. Weak Thigh Muscles: Not having enough strength in your thigh muscles.
  5. Tight Hamstrings and Achilles Tendons: Having tight muscles at the back of your thigh or in the tendons connecting your lower leg to your heel.

Most of the time, you can ease runner’s knee by resting, using over-the-counter pain relievers, and giving your knee some time to heal. With the right care, this condition often gets better within a few weeks.

2. Osteoarthritis

Osteoarthritis is a long-lasting condition that’s different from minor cases of runner’s knee, which usually get better on their own. To deal with osteoarthritis, you should talk to your healthcare provider about a plan for managing it over the long term.

In a healthy knee, soft tissues, like cartilage, act as cushions between the thighbone, shinbone, and kneecap. These tissues help your knee handle your body weight when you walk and allow for smooth movement. The cartilage in your knee ensures that your knee joint can bend without the bones rubbing together.

However, in osteoarthritis of the knee, these soft tissues gradually break down. This causes the bones in your knee joint to rub against each other, leading to irritation, swelling, and pain.

The pain from osteoarthritis can come and go. It often feels like stiffness or a dull ache when you bend your knee or stand. You might also experience swelling and a throbbing feeling, which can be more noticeable at night.

Although there’s no cure for osteoarthritis because it’s not possible to fully repair or replace the damaged joint tissue, there are treatments available to help manage pain and prevent further damage to the knee for people with this condition.

3. Rheumatoid Arthritis

Rheumatoid Arthritis (RA) is a long-lasting condition where your body’s defense system mistakenly attacks your joints, including your knees. It causes pain and makes it harder to move your knees.

Although there’s no cure for RA, there are many ways to help you feel better and move more easily. You can use medications, reduce strain on your joints, get physical therapy, and sometimes, have surgery. These treatments can improve your life even though RA can’t be completely cured.

4. Post-Traumatic Arthritis

Post-traumatic arthritis happens after a knee injury, like a broken bone or damage to the knee joint. It can also show up years later due to things like meniscus tears, ligament damage, or just getting older.

People with this type of arthritis feel pain, stiffness, and swelling in their knee. Sometimes, the pain gets worse with certain weather changes or after a long rest, like sleeping at night.

5. Bursitis

Bursitis is a condition that can cause pain and swelling in your knee, either over the kneecap or on the side. To understand bursitis, let’s take a closer look at how your knee works.

Inside your knee, there are small sacs filled with fluid called bursae. These sacs help tendons move smoothly over your joints. But in cases of bursitis, these sacs get irritated and swell up, which puts pressure on the surrounding knee structures and leads to pain.

There are various causes of bursitis, similar to what can lead to runner’s knee. One common cause is putting too much pressure on your knee, like kneeling or squatting without proper knee protection. Bursitis can also result from a direct injury to your knee.

It’s important to know that while bursitis is somewhat similar to runner’s knee in terms of being an overuse injury, it’s not as common.

Bursitis comes with specific symptoms that set it apart from runner’s knee. These symptoms often include a swollen kneecap, pain when you bend your knee, and sometimes, more discomfort at night.

6. Gout

Gout is a painful kind of arthritis that can affect any joint in your body, but it usually targets the big toe. It happens when your body has too much uric acid, leading to sharp crystals forming in your joints. These crystals cause sudden and severe pain, along with swelling and tenderness.

Common signs of gout include intense pain, redness, swelling, and warmth in the joint that’s affected. Gout attacks can come out of nowhere, lasting for days or even weeks. Afterward, there can be long periods without symptoms, lasting for weeks, months, or even years.

7. Growing Pains

Knee pain is a common problem for teenagers who are still growing. One of the main culprits behind this pain is Osgood-Schlatter disease. Don’t worry, despite the scary-sounding name, it’s not really a disease. Instead, it’s an inflammation that happens just below the knee where the tendon connects the kneecap to the shinbone.

This knee discomfort usually shows up during growth spurts, when your bones, muscles, tendons, and other body parts are changing rapidly. The good news is that you can make this knee pain go away with some simple steps. Rest, applying ice, and using over-the-counter pain relievers, along with doing stretching and strengthening exercises, can all help make the pain more manageable.

8. Other Knee Injuries and Conditions

Your knee is the biggest joint in your body, which makes it vulnerable to injuries and strain. If you happen to fall or bump your knee, you might experience pain and bruising.

Additionally, if any of the three knee bones break, you may feel weakness, sharp pain, or deep throbbing sensations.

Why Knee Pain Gets Worse at Night

Knee pain can become more noticeable at night, even if it was improving during the day. There are a few reasons for this:

  1. Rest Makes You Aware: When you’re resting, you might notice mild to moderate knee pain that you didn’t feel during the busy day. Your body also produces less cortisol during sleep, which can help with inflammation. But since many knee pains are linked to inflammation, having lower cortisol levels at night can make it harder for your body to manage swelling and discomfort in your knees.
  2. Nighttime Stiffness: During sleep, your joints stay still for a long time, which can make them feel stiff and less flexible when you wake up. Moving a bit, even with gentle exercises like walking, swimming, or yoga, can keep your joints flexible, your tendons limber, and help circulate the fluid that protects your knee joints. People with chronic conditions like arthritis often have less pain when they follow a regular exercise routine recommended by their doctor.
  3. Lack of Sleep Makes It Worse: Knee pain can create a cycle where it keeps you awake at night, and the lack of sleep makes your pain worse. Sleep is vital for your body’s healing and recovery. Without enough sleep, your body has less energy for healing because it has to focus on staying alert. If nighttime knee pain leads to restless sleep, you might end up straining your knee more by sleeping in uncomfortable positions.

When to See a Doctor for Knee Pain at Night

If you’ve had knee surgery or an injury, it’s common to experience nighttime knee pain. A few nights of discomfort are usually okay, but there are times when you should consult a doctor:

  1. Unusual or significant swelling in the knee.
  2. Persistent redness after an injury.
  3. If you have a fever.
  4. Increasing and severe pain.
  5. Feeling warmth in the joint.
  6. Tender when touching the affected area.

In some cases, you need immediate medical attention if:

  1. Your knee looks deformed.
  2. Pain makes it impossible to put weight on your leg.
  3. You heard a pop during an injury.
  4. Sudden and severe swelling.

If your nighttime knee pain consistently disrupts your sleep and worsens your daytime discomfort, you need to address it promptly. Poor sleep can slow healing after knee surgery. If pain lasts for three to four days or intermittently for a week or two, schedule a follow-up with your doctor.

How to Relieve Knee Pain at Night

If you’re dealing with knee pain when trying to sleep, there are various methods to help you feel better. Here’s how to ease nighttime knee pain:

  1. Ice or Heat Packs: Use ice for recent injuries and heat for ongoing problems. Apply them for 10-20 minutes before bedtime.
  2. Elevate Your Legs: Raise your legs with pillows for 20 minutes to reduce knee swelling.
  3. Comfortable Sleep Position: Use a pillow between your knees if you sleep on your side or under your knee if you sleep on your back. Make sure you have a supportive mattress.
  4. Take a Warm Bath: A warm bath relaxes and soothes achy knees.
  5. Relaxation Techniques: Listen to calming music, practice deep breathing, or use meditation apps like Headspace.
  6. Medication: Consult your doctor for over-the-counter pain relievers and anti-inflammatories. Take them 30 minutes before bedtime. Discuss slow-release options if knee pain wakes you at night.
  7. Healthy Sleep Habits: Keep electronics out of your bedroom, stick to a consistent sleep schedule, aim for 8 hours of sleep, consider blackout curtains, and avoid caffeine in the afternoon and evening.
  8. Topical Treatment: Talk to your doctor about gels, creams, sprays, or patches like the Wellnee Pain Relief Patch for direct knee pain relief. Wellnee patches utilize natural herbal ingredients, such as mugwort, known for their pain-relieving properties. The patches are designed to be applied directly to the skin over the affected area, releasing their active ingredients slowly to provide sustained relief.
  9. Regular Rests: Elevate your legs during the day to reduce swelling.
  10. Compression Wraps: Use compression wraps or knee sleeves during the day for support, but don’t wear them at night.
  11. Walking Aids: Consider a walking stick or crutches to relieve knee pressure during the day.
  12. Massage: Schedule a massage during the day or before bedtime to relax and reduce pain.
  13. Supplements: Ask your doctor about supplements like omega-3, SAM-e, or feverfew for arthritis-related knee pain.
  14. Quit Smoking: Smoking hinders healing by affecting blood circulation.
  15. Stretch: Do gentle stretching exercises before bedtime and after waking up to relieve tension and improve blood flow to your knees.
