Medical experts have identified various causes and warning signs associated with knee pain, ranging from common age-related wear to serious underlying conditions.

Initial reports highlight that while osteoarthritis and overuse are frequent causes of pain in adults over 40, specific patterns such as pain that is “worse at rest than during activity” or pain that “wakes a person up at night” require immediate medical investigation. Such symptoms can occasionally indicate more serious issues, including bone tumors like chondrosarcoma.

Further information details that severe morning stiffness and difficulty walking can be attributed to rheumatoid arthritis, gout, or pseudogout. Medical attention is considered urgent if an individual cannot bear weight on the knee or if the pain is accompanied by swelling, redness, heat, fever, chills, or visible deformity.
