What happens when your knee hurts all the time?

Chronic knee pain can have several causes, and it's important to get a proper diagnosis from a healthcare professional. Some common reasons why your knee may hurt all the time include:

1. Osteoarthritis: This is a degenerative joint disease that causes the cartilage in your knee to wear down over time. Osteoarthritis is often associated with aging and obesity.

2. Rheumatoid arthritis: This is an autoimmune disease that causes inflammation in the joints, including the knees.

3. Meniscus tears: The meniscus is a C-shaped piece of cartilage that cushions your knee joint. Meniscus tears can be caused by acute injuries or wear and tear over time.

4. Ligament injuries: The ligaments in your knee help to stabilize the joint. Ligament injuries can be caused by trauma or repetitive stress.

5. Bursitis: This is an inflammation of the bursae, small fluid-filled sacs that help to cushion the joints. Bursitis can be caused by overuse, trauma, or certain medical conditions.

6. Tendonitis: This is an inflammation of the tendons, which are the tissues that connect muscles to bones. Tendonitis can be caused by overuse or repetitive motion.

7. Fractures: If you have broken a bone in your knee, it can cause pain that lasts for a long time.

8. Referred pain: Pain from other areas of the body, such as the hip, back, or pelvis can sometimes be felt in the knee.

If you're experiencing chronic knee pain, consult a healthcare professional for a diagnosis and proper treatment. They may recommend treatments such as medication, physical therapy, bracing, or surgery, depending on the underlying cause of your pain.
