Joints are the parts of your body where your bones meet. Joints allow the bones of your skeleton to move. Joints include:
Joint pain refers to discomfort, aches, and soreness in any of the body’s joints. Joint pain is a common complaint. It doesn’t typically require a hospital visit. Sometimes, joint pain is the result of an illness or injury. Arthritis is also a common cause of joint pain. However, it can also be due to other conditions or factors.
What Causes Joint Pain?One of the most common causes of joint pain is arthritis. The two main forms of arthritis are osteoarthritis (OA) and rheumatoid arthritis (RA).
According to the American College of Rheumatology, OA is most common in adults over the age of 40. It progresses slowly and tends to affect commonly used joints like the:
Joint pain due to OA results from a breakdown of the cartilage that serves as a cushion and shock absorber for the joints.
The second form of arthritis is RA. According to the Arthritis Foundation, RA affects about 1.5 million Americans. It more commonly affects women than men. It can deform and debilitate the joints over time. RA causes pain, inflammation, and fluid buildup in the joints as the body’s immune system attacks the membrane that lines the joints.

Your doctor will probably perform a physical exam. They’ll also ask you a series of questions about your joint pain. This may help to narrow down the potential causes.
A joint X-ray may be necessary to identify arthritis-related joint damage. If your doctor suspects there’s another cause, they may perform a blood test to screen for certain autoimmune disorders. They may also perform a sedimentation rate test to measure the level of inflammation in the body or a complete blood count
