Joint pain can have multiple causes, but can often be accompanied by loss of range-of-motion, stiffness, inflammation, swelling, localized heat/redness and muscle weakness. Age can cause joint degeneration, but the most common cause of joint pain is arthritis. There are various types of arthritis with their own accompanying symptoms, but the one defining symptom that is present in all types of arthritis is joint pain. Arthritis affects more than 42 million individuals in the United States, with the most common types being osteoarthritis and rheumatoid arthritis.
While most joint pain cases can be linked to arthritis, there are other factors that can cause joint pain. Injuries to the joint that either did not heal correctly or were not treated properly can cause pain that will continue past the expected time of healing.
