[52F] Experiencing knee pain with grinding sensation

What might be happening

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

• Osteoarthritis: This is a common form of arthritis that often affects the knees. It occurs when the protective cartilage that cushions the ends of your bones wears down over time. Symptoms can include pain, stiffness, and a grating or grinding sensation when you move the joint.

  • Treatment typically involves a combination of exercise, weight loss if you're overweight, pain relievers and anti-inflammatory drugs, and physical therapy. In severe cases, surgery may be recommended.

• Patellofemoral pain syndrome: This condition causes pain in the front of the knee and around the kneecap. It's often seen in people who participate in sports, but it can also occur in non-athletes. The pain is usually worse when going up or down stairs, squatting, or sitting with the knee bent for a long time.

  • Treatment usually involves physical therapy and pain relievers.

• Meniscus tear: This is a common injury in which forceful twisting causes certain tissue in the knee to tear. However, in your case, this is less likely since you didn't mention any specific injury event.

  • Treatment may include physical therapy, a brace, or in some cases, surgery.

What you can do

You should definitely see a healthcare provider for a proper diagnosis and treatment plan. In the meantime, here are some things you can do:

1. Rest your knee as much as possible.
2. Apply ice to your knee for 15 minutes, several times a day.
3. Elevate your leg on a pillow when you sit or lie down.
4. Take over-the-counter pain relievers, such as ibuprofen (Advil, Motrin IB) or acetaminophen (Tylenol).

What you should look out for

You should seek immediate medical attention if:

• The pain is severe or sudden.
• Your knee is severely swollen.
• You cannot move your knee.
• You cannot bear weight on your knee.
