Are Your Swollen Glands a Symptom of Rheumatoid Arthritis?
[ad_1]
You have hundreds of lymph nodes throughout your body, and large clusters of them in three particular areas: your neck, your armpits, and your groin.
Lymph nodes (also known as glands) filter waste out of lymph fluid, which contains white blood cells that help fight infection, notes the Cleveland Clinic. In a nutshell, lymph nodes help keep you healthy.
Lymph Nodes May Become Enlarged
When lymph nodes become swollen or enlarged, doctors refer to the condition as lymphadenopathy. Sometimes the swelling is localized (in only one place in the body), and sometimes it is diffuse (throughout the body).
A lump that you see or feel, especially in your neck, armpit, or groin, can be a symptom of lymphadenopathy. Some swollen lymph nodes are only slightly noticeable. The lump may or may not be tender or painful, and you may feel one lump or several. Swollen glands may accompany a sore throat — which can cause painful swallowing and may feel like there is a soreness, discomfort, pain, or scratchiness in the throat — depending on the cause of the pain.
If you’ve ever experienced this symptom and you have rheumatoid arthritis (RA), you may have wondered whether the two are related.
According to Scott Zashin, MD, an internist and rheumatologist in Dallas, there are several common causes of lymphadenopathy, and most are not directly related to rheumatoid arthritis. But some are in the same general category of rheumatic diseases as RA.

Is RA Behind the Swelling in Your Lymph Nodes? Probably Not
Dr. Zashin explains some of the possible root causes of swollen glands:
- An Infection Both viral and bacterial infections can cause lymph node swelling, including strep throat, COVID-19, or the common cold, which can include a sore or scratchy throat, a stuffy or runny nose, sneezing, coughing, a headache, aching joints or fatigue, measles, mononucleosis, an ear infection, a tooth infection, HIV, or a skin infection. If the trigger is a bacterial infection, you may need an antibiotic. If it’s a viral infection, you may just have to wait it out.
- Sjögrens Syndrome Some people who have inflammatory arthritis also develop Sjögren’s syndrome. Common symptoms of this autoimmune disease include dry eyes, mouth, and skin, as well as swelling of the parotid glands, located in front of and below the ears, notes the Mayo Clinic. Some people with Sjögren’s syndrome may have enlarged lymph nodes, notes the Arthritis Foundation.
- Still’s Disease This form of inflammatory arthritis is rare in adults, but people with adult-onset Still’s disease may develop lymphadenopathy. People with Still’s disease who have swollen lymph nodes may also have a fever, rash, and an enlarged liver, notes research published in the International Journal of Molecular Sciences.
- Cancer Many kinds of cancer can cause swollen lymph nodes. People who have rheumatoid arthritis, as well as those who have Sjögren’s syndrome, are at a slightly higher risk of developing lymphoma, a cancer of the lymphatic system, compared with those who don’t have these conditions. “Lymphoma is not common with rheumatoid arthritis, but it does correlate with disease activity. So the higher the disease activity, the higher the risk of lymphoma,” says Zashin. While early studies hinted that some drugs used to treat RA, known as biologics, might increase lymphoma risk, subsequent longitudinal studies, where researchers studied patients over a period of time, have not confirmed this risk, notes the Arthritis Foundation. Beyond swollen nodes, other common symptoms of lymphoma include weight loss, rash, fever, and unusual fatigue or bleeding.
- Very Active, Uncontrolled Rheumatoid Arthritis, Especially if the Condition Has Lasted for Many Years “It’s rare, but you can sometimes see lymph node enlargement related to rheumatoid arthritis activity,” Zashin says. “This is usually more of a diagnosis of exclusion.” In other words, your doctor will probably want to rule out other possible causes of swollen glands first, such as infection or cancer, before blaming your rheumatoid arthritis. “I would refer a patient to an oncologist, unless I saw an obvious reason for it, like if the patient has mono or another infection,” he says.

Treating Swollen Lymph Nodes
Treatment of swollen lymph nodes varies widely, depending on the cause. If you alert your doctor to your symptoms right away, you can work together to figure out next steps. You might be prescribed antibiotics, advised to watch your condition to see if it gets worse, or be called into the office for a biopsy. Whether the cause is serious or not, your doctor can help steer you in the right direction and get you feeling your best again.
