Your knee pain can take a variety of forms, ranging from an occasional twinge while running. to an unrelenting ache. Although arthritis is the leading cause of knee joint deterioration, pain, and limited movement, sports injuries and work-related injuries can also cause knee problems.
As is the case with pain in other locations, very mild pain associated with less involved musculoskeletal knee injuries can feel itchy or irritated. When pain progresses, injured knees can feel hot, swollen, or stiff. Such painful knees are often also stiff, unstable, weak, noisy and difficult to bend. Knee injuries can hinder your mobility and rob you of the ability to participate in sports, complete errands or household tasks, and even sleep.
