Knee pain at night is a common and bothersome symptom that can make it difficult to fall asleep and stay asleep. It can be caused by a variety of factors, including arthritis, injury, bursitis, gout, pseudogout, overuse, infection, tumor, referred pain, and pregnancy.
Arthritis is the most common cause of knee pain at night, especially in older adults. It is a condition characterized by inflammation of the joints. There are many different types of arthritis, including osteoarthritis, rheumatoid arthritis, and psoriatic arthritis.
Injury to the knee can also cause pain at night. This can include injuries such as a torn meniscus, ACL tear, or patellar tendinitis. Knee injuries can occur during sports, exercise, or everyday activities.
Bursitis is inflammation of the bursae, which are small fluid-filled sacs that cushion the bones, tendons, and muscles around the knee joint. Bursitis can be caused by overuse, injury, or infection.
Gout is a type of arthritis that is caused by a buildup of uric acid crystals in the joints. Gout attacks can cause sudden and severe pain in the knee, especially at night. Gout attacks are often triggered by certain foods and drinks, such as red meat, seafood, and alcohol.
Pseudogout is a type of arthritis that is caused by a buildup of calcium pyrophosphate dihydrate crystals in the joints. Pseudogout attacks can cause pain, swelling, and redness in the knee, especially at night. Pseudogout attacks are often triggered by trauma or surgery.
Overuse of the knee can also cause pain at night. This is common in runners and other athletes. Overuse can lead to inflammation and damage to the tendons, muscles, and other tissues around the knee joint.
Infection of the knee joint, also known as septic arthritis, can also cause pain at night. Knee infections can occur from a break in the skin, such as from a cut or scrape, or from the spread of infection from another part of the body.
Tumor in the knee joint can also cause pain at night. Tumors can be benign (non-cancerous) or malignant (cancerous).
Referred pain is pain that is felt in one part of the body but is caused by a problem in another part of the body. For example, pain from a hip problem can sometimes be referred to the knee.
Pregnancy is another common cause of knee pain at night. The extra weight and changes in hormones during pregnancy can put extra stress on the knee joints.
