Joints are the parts of your body where your bones meet. Joints allow the bones of your skeleton to move. Joints include:

shoulders
hips
elbows
knees
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.

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:

wrists
hands
hips
knees
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.

Other Causes

Joint pain can be caused by:

bursitis, or inflammation of the cushioning pads around joints
lupus
gout
certain infectious diseases, such as mumps, influenza, and hepatitis
chondromalacia of the patella, or a breakdown of the cartilage in the kneecap
an injury
tendinitis, or inflammation of the tendon
an infection of the bone
overuse of a joint
cancer
fibromyalgia
osteoporosis
sarcoidosis
rickets

In some cases, your joint pain will require you to see a doctor. You should make an appointment if you don’t know the cause of your joint pain and are experiencing other unexplained symptoms. You should also see a doctor if the area around the joint is swollen, red, tender, or warm to the touch, the pain persists for three days or more, or you have a fever but no other signs of the flu.

Go to the emergency room if any of the following occurs:

You’ve experienced a serious injury.
The joint appears deformed.
Swelling of the joint occurs suddenly.
The joint is completely immobile.
You have severe joint pain.

Home Treatment

Doctors consider both OA and RA to be chronic conditions. Nothing can eliminate the joint pain associated with arthritis or keep it from returning. However, there are ways to manage the pain:

It may help to use topical pain relievers or take nonsteroidal anti-inflammatory drugs to reduce pain, swelling, and inflammation.
Stay physically active and follow a fitness program focusing on moderate exercise.
Stretch before exercising to maintain a good range of motion in your joints.
Keep your body weight within a healthy range. This will lessen stress on the joints.
If your pain isn’t due to arthritis, you can try taking a nonprescription, anti-inflammatory drug, getting a massage, taking a warm bath, stretching frequently, and getting adequate rest.
Medical Treatment

Your treatment options will depend on the cause of the pain. In some cases, your doctor will need to draw out accumulated fluid in the joint area. They might also recommend surgery to replace the joint.

Other nonsurgical treatment methods could include lifestyle changes or medications that can potentially cause your RA to go into remission. In the case of RA, your doctor will first address inflammation. Once the RA goes into remission, your medical treatment will focus on keeping a tight rein on your condition so that you avoid flare-ups.

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.

Joint pain is often a result of the damage that occurs through normal wear and tear. However, it can also be a sign of an infection or potentially debilitating RA.

You should see your doctor if you have any unexplained joint pain, especially if it doesn’t go away on its own after a few days. Early detection and diagnosis can allow for effective treatment of the underlying cause of your discomfort.
