[32F] Experiencing knee pain with instability

What might be happening

Based on the symptoms you've described, here are some possible causes for your knee pain:

• Patellofemoral Pain Syndrome: This condition is often caused by overuse, injury, or muscle imbalances and can cause pain around the kneecap. It's often worse when going down stairs or after sitting for a long time.

  • Treatment usually involves physical therapy to strengthen the muscles around your knee and improve flexibility.

• Meniscus Tear: The meniscus is a piece of cartilage that provides a cushion between your femur (thighbone) and tibia (shinbone). Tears are often caused by twisting or turning quickly, with the foot planted while the knee is bent. Meniscus tears often cause pain, swelling, stiffness, and a tendency for your knee to give way or lock up.

  • Treatment may involve physical therapy, or in some cases, surgery.

• Osteoarthritis: This is a common form of arthritis that occurs when the protective cartilage on the ends of your bones wears down over time. It can cause pain, swelling, and reduced motion in your joints.

  • Treatment usually involves medication to reduce pain and inflammation, physical therapy, and in some cases, surgery.

Please note that these are potential causes based on the symptoms you've described. It's important to see a healthcare professional for a proper diagnosis.

What you can do

While waiting for your appointment, here are some things you can do to help manage your knee pain:

1. Rest and elevate your knee when possible, especially if it's swollen.
2. Apply a cold pack to your knee for 15 minutes at a time, several times a day.
3. Over-the-counter pain relievers such as ibuprofen can help reduce pain and inflammation.
4. Gentle exercises can help strengthen the muscles around your knee. Try straight-leg raises and other low-impact aerobic exercises.

What you should look out for

Please seek immediate medical attention if you experience:

• An inability to bear weight on your knee
• Noticeable deformity in your leg or knee
• Unbearable pain
• Sudden swelling
• Signs of an infection, including fever, redness, warmth
