Morning Stiffness That Won’t Quit Is One of 6 Signs of Rheumatoid Arthritis Many People Mistake for Everyday Aches

By Mike Harper · October 23, 2026

Achy joints can feel like a normal part of getting older, and many people simply live with them. Often the cause is osteoarthritis, the most common type of arthritis. But some aches come from rheumatoid arthritis, a different disease that is worth catching early.

Rheumatoid arthritis, or RA, is an autoimmune disease. The immune system attacks the body’s own tissues, and the National Institute of Arthritis and Musculoskeletal and Skin Diseases says it causes pain, swelling, stiffness, and loss of function in joints. Mayo Clinic explains the difference this way: osteoarthritis damages joints from overuse, while RA affects the lining of the joints and eats away at the bone under them, which can bend joints out of shape over time. Some people have both.

Age does not rule it out. The CDC says RA risk rises as people get older and is highest among adults 50 to 59, and women are two to three times more likely to have it. These are the six signs to watch for.

Morning stiffness that lingers. NIAMS lists joint stiffness that lasts longer than 30 minutes, typically after waking or after resting for a long time. Mayo says it can last 45 minutes or longer. By comparison, NIAMS says osteoarthritis stiffness usually lasts less than 30 minutes.

Warm, swollen, tender joints. RA joints are often painful at rest as well as when moving, and they may feel warm or look puffy. NIAMS says the swelling can make it hard to make a fist, comb your hair, button clothes, or bend your knees.

Small joints first. Mayo says RA may affect just a few joints at first, most often the small joints of the hands and feet. Over time it can spread to the wrists, elbows, hips, knees and ankles.

The same joints on both sides. RA often follows a symmetrical pattern. If your right hand is affected, NIAMS says, your left hand may be too. Mayo’s Dr. Nisha Manek says pain, swelling and stiffness that comes and goes and is on both sides of the body is a reason to see your doctor.

Unusual tiredness. Fatigue is on the symptom lists from NIAMS, Mayo and the CDC. Feeling worn out with no clear reason is easy to pin on age or poor sleep.

Low fever, poor appetite or weight loss. NIAMS lists occasional low-grade fever and loss of appetite, and the CDC includes fever and weight loss. These whole-body symptoms are a clue that something more than everyday aches may be going on.

Symptoms can come and go. Mayo describes flares, when the disease is more active, followed by periods of remission. That on-and-off pattern is one reason RA can be slow to get diagnosed.

Early treatment matters. The CDC says it is best to diagnose and treat RA early to avoid joint damage and worsening symptoms. Doctors use a physical exam, X-rays, lab tests and your health history to make the diagnosis, and the CDC says rheumatologists should diagnose and treat it. Medicines called DMARDs can slow the disease, control swelling and help keep joints from becoming deformed.

Mayo recommends making an appointment if you have ongoing pain and swelling in your joints that is not getting better after several weeks.
