Rheumatoid arthritis (RA) is an autoimmune disease that can cause joint pain and damage throughout your body. The joint damage that RA causes usually happens on both sides of your body. So if a joint is affected in one of your arms or legs, the same joint in the other arm or leg will probably be affected, too. This is one way that doctors distinguish RA from other forms of arthritis, such as osteoarthritis (OA).
Treatments work best when RA is diagnosed early, so it’s important to learn the signs. Read on to learn everything you want to know about RA, from types and symptoms, to home remedies, diets, and other treatments.
RA is a long-term or chronic disease marked by symptoms of inflammation and pain in the joints. These symptoms and signs occur during periods known as flares. Other times are known as periods of remission — this is when symptoms dissipate completely.
RA symptoms, which can occur throughout the body, include:
Symptoms can vary from mild to severe. It’s important not to ignore your symptoms, even if they come and go. Knowing the early signs of RA will help you and your doctor to better treat it.
Diagnosing RA can take time and may require multiple lab tests to confirm clinical examination findings. Your doctor will use several tools to diagnose RA.
First your doctor will ask about your symptoms and medical history. They’ll also perform a physical exam of your joints. This will include looking for swelling and redness, and testing your reflexes and muscle strength. Your doctor will also touch the affected joints to check for warmth and tenderness. If they suspect RA, they’ll most likely refer you to a specialist called a rheumatologist.
Since no single test can confirm a diagnosis of RA, your doctor or rheumatologist may use several different types of tests. They may test your blood for certain substances like antibodies, or check the level of certain substances like acute phase reactants that are elevated during inflammatory conditions. These can be a sign of RA and help support the diagnosis.
They may also request certain imaging tests. Tests such as ultrasonography, x-ray exams, and magnetic resonance imaging (MRI) not only show if damage from RA has been done to your joints but also how severe the damage is. A complete evaluation and monitoring of other organ systems might be in order for some people with RA, too. Learn more about the process of diagnosing RA.
There are several types of blood tests that help your doctor or rheumatologist determine whether you have RA. These tests include:
There’s no cure for RA, but there are treatments that can help you to manage it. Treatments for RA help to manage the pain and control the inflammatory response which can in many cases result in remission. Decreasing the inflammation can also help to prevent further joint and organ damage.
Treatments may include:
Your doctor will work with you to determine the best types of treatments for you. For many people, these treatments can help them live an active life and reduce the risk of long-term complications. Learn more about specific RA treatments and how to treat flares.
There are many types of medication for RA. Some of these medications help to reduce the pain and inflammation of RA. Some help to reduce flares and limit the damage that RA does to your joints.
The following medications help reduce the pain and inflammation during RA flares:
The following drugs work to slow the damage that RA can cause to your body:

Certain home remedies and lifestyle adjustments may help to improve your quality of life when living with RA:
Low-impact exercises can help to improve the range of motion in your joints and increase your mobility. Exercise can also strengthen muscles, which can help to relieve some of the pressure from your joints. You can also try gentle yoga, which will help you regain strength and flexibility.
You may need more rest during flare-ups and less during remission. Getting enough sleep will help to reduce inflammation and pain as well as fatigue.
Ice packs can help to reduce inflammation and pain. They may also be effective against muscle spasms. You can alternate cold with hot treatments such as warm showers and hot compresses. These treatments may help to reduce stiffness.
Certain devices such as splints and braces can hold your joints in a resting position. This may help to reduce inflammation. Canes and crutches can help you maintain mobility, even during flares. You can also install household devices, such as grab bars and handrails in bathrooms and along staircases.
Your doctor or dietitian may recommend an anti-inflammatory diet for you to help with your symptoms. This type of diet includes foods that have lots of omega-3 fatty acids.
Foods high in omega-3 fatty acids include:
Antioxidants, such as vitamins A, C, and E, and selenium, may also help reduce inflammation. Foods high in antioxidants include:
Eating lots of fiber is also important, because according to some researchers, fiber may help reduce inflammatory responses which can be seen as a decrease in C-reactive protein levels. Choose whole grain foods, fresh vegetables, and fresh fruit. Strawberries may be particularly beneficial.
Foods containing flavonoids can also help to counter inflammation in the body. They include:
What you don’t eat is just as important as what you do eat. Make sure to avoid trigger foods. These include processed carbohydrates and saturated or trans fats. Avoiding trigger foods and choosing the right foods to follow an anti-inflammatory diet may help you manage your RA.
There are several different types of RA. Knowing which type you have may help your doctor provide the best type of treatment for you. Types of RA include:
Seropositive RA is the most common type of RA. This type of arthritis may run in families. Seropositive RA may come with more severe symptoms than seronegative RA. Presenting symptoms of seropositive RA can include:
RA isn’t always confined to the joints and some people with seropositive RA can experience inflammation in the eyes, salivary glands, nerves, kidneys, lungs, heart, skin, and blood vessels.
The cause of RA isn’t known. However, certain factors seem to have a role in increasing the risk of developing RA or triggering its onset. Factors that increase risk of RA include:
Factors that may trigger onset of RA include:
Arthritis in the hands may start as a low-level burning sensation that you feel at the end of the day. Eventually, you may experience pain that isn’t necessarily from using your hands. This pain can get quite severe if you don’t treat it. You may also feel swelling, redness, warmth, and stiffness. If the cartilage in your joints wears away, you may notice some deformities in your hands. You may also have a grinding feeling in the joints of your hands, fingers, and large joints, if the cartilage deteriorates completely.
As the disease progresses, fluid-filled sacs or synovial cysts may develop in the wrists and around the joints of the hands. These cysts aren’t without complications and tendon rupture can occur in some cases. You may also develop knobby growths, called bone spurs, in the affected joints. Over time, bone spurs can make it harder for you to use your hands.
If you have RA in your hands, your doctor will work with you on exercises which can help you to retain movement and function. These, along with other types of treatment, can help reduce inflammation and stave off progression of the disease. See exactly what the effects of RA looks like on your hands.
RA may be most visible in your hands and feet, particularly as the disease progresses and especially if you don’t have treatment. Swelling of fingers, wrists, knees, ankles, and toes are common. Damage to ligaments and swelling in the feet can cause a person with RA to have trouble walking.
If you don’t get treatment for RA, you may develop severe deformities in your hands and feet. Deformities of the hands and fingers may cause a curved, claw-like appearance. Your toes can also take on a claw-like look, sometimes bending upward, and sometimes curling under the ball of the foot. You may also notice ulcers, bunions, and calluses on your feet.
Lumps, called rheumatoid nodules, can appear anywhere on your body where joints are inflamed. These can range in size from very small to the size of a walnut or larger, and they can occur in clusters. This is what rheumatoid nodules and other visible signs of RA look like.
Like RA, people with OA can experience painful and stiff joints that can make moving around difficult. People with OA may have joint swelling after extended activity, but OA doesn’t cause any significant inflammatory reaction that typically results in redness of the affected joints.
Unlike RA, OA isn’t an autoimmune disease. It’s related to the natural wear and tear of the joints as you age or it can develop as a result of trauma. OA is most often seen in older adults. However, it can sometimes be seen in younger adults who overuse a particular joint — such as tennis players and other athletes — or those who have experienced a severe injury.
RA is an autoimmune disease. The joint damage from RA isn’t caused by normal wear and tear but by your body attacking itself. Learn more about these two types of arthritis.
Rheumatoid arthritis isn’t considered a hereditary disease, yet it does appear to run in families. This may be due to environmental causes, genetic causes, or a combination of both. If you have family members who have or have had RA, talk to your doctor, especially if you have any symptoms of persistent joint pain, swelling, and stiffness, unrelated to overuse or trauma.
Having a family history of RA increases your risk of getting the disease, and early diagnosis can make a big difference in how effective treatment will be. So can you inherit RA? Maybe — learn more here.
RA is a chronic disease that doesn’t currently have a cure. That said, most people with RA don’t have constant symptoms. Instead, they have flare-ups followed by relatively symptom-free periods, called remissions. The course of the disease varies from person to person and symptoms can range from mild to severe.
Though symptoms may stop for extended periods, joint problems caused by RA will usually get worse over time. That’s why early treatment is so important to help delay serious joint damage. If you’re experiencing any symptoms or have concerns about RA, talk to your doctor.
