[55F] Experiencing severe left knee pain with popping sound

What might be happening

Based on the information you've provided, possible causes for your knee pain include:

• Meniscal tear: The meniscus is a piece of cartilage that provides a cushion between your thighbone and shinbone. A tear is often caused by a sudden twist or quick turn, and is common in sports. The popping sound you heard, followed by pain, is a common symptom of a meniscal tear.

  • Treatment typically includes rest, ice, compression, and elevation (RICE). In some cases, physical therapy or surgery may be necessary.

• Ligament injuries: The knee has four main ligaments, and these can be sprained or torn if the knee is twisted or hit with force. This could potentially happen when rolling over in bed.

  • Treatment usually involves RICE, physical therapy, and in some cases, surgery.

• Patellar dislocation: This is when the kneecap slides out of position, causing knee pain and swelling. This could potentially happen from a strange movement or twist.

  • Treatment typically involves reducing the dislocation, immobilizing the knee, and physical therapy.

Please note that these are possibilities based on the information provided, and only a healthcare professional can provide a definitive diagnosis.

What you can do

1. Rest: Avoid putting weight on your knee as much as possible.
2. Ice: Apply an ice pack (or a bag of frozen peas) to your knee for 15 minutes every two hours.
3. Compression: Use a compression bandage to help reduce swelling.
4. Elevation: Try to keep your knee raised above the level of your heart as much as possible to help reduce swelling.

You should also make an appointment with your healthcare provider as soon as possible for a proper evaluation and diagnosis.

What you should look out for

Please seek immediate medical attention if:

• Your knee pain is severe or sudden
• You can't move your knee or leg
• You can't bear weight on your leg
• Your knee looks deformed or has an obvious fracture
• You have a fever, redness, or warmth around the knee, which could indicate an infection
