Arthritis causes joint pain, stiffness, swelling, and reduced range of motion. These are the core symptoms across more than 100 types of arthritis, but the specific pattern, timing, and severity vary depending on which type you’re dealing with. Some forms stay limited to the joints, while others cause bodywide symptoms like fatigue, fever, and skin changes.
Symptoms Common to Most Types
Regardless of the specific type, arthritis typically shows up as some combination of five key symptoms: pain in or around a joint, stiffness (especially in the morning or after sitting still), visible swelling, warmth or skin discoloration over the joint, and difficulty moving the joint through its full range. These symptoms can affect any joint in the body, from fingers and toes to knees, hips, shoulders, and the spine.
The pain can range from a dull ache to sharp, intense discomfort that interferes with everyday tasks like opening jars, climbing stairs, or getting dressed. Many people first notice that activities they used to do without thinking now require effort or cause soreness afterward.
Morning Stiffness: A Key Clue
How long your joints feel stiff in the morning tells you a lot about what’s going on. In inflammatory types of arthritis like rheumatoid arthritis, morning stiffness typically lasts longer than 60 minutes. You wake up feeling locked up, and it takes an hour or more of movement before your joints loosen. With osteoarthritis, stiffness tends to be shorter, often easing within 15 to 30 minutes of getting moving. If your morning stiffness consistently lasts more than an hour, that’s a signal worth bringing to your doctor.
Osteoarthritis Symptoms
Osteoarthritis is the most common form, driven by wear and breakdown of the cartilage cushioning your joints. It tends to develop gradually over months or years. The joints most often affected are the knees, hips, hands (especially the base of the thumb and the finger joints closest to the nail), and the spine. Pain typically worsens with activity and improves with rest, at least in earlier stages. You may hear or feel a grating, crackling sensation when you move the joint.
Although osteoarthritis has traditionally been described as an asymmetrical condition, affecting one side more than the other, research shows that many people actually experience it on both sides. A study in the Annals of the Rheumatic Diseases found that bilateral involvement was more common than one-sided disease in the fingers, knees, ankles, and toes. So if both of your knees ache rather than just one, osteoarthritis is still very much a possibility.
Rheumatoid Arthritis Symptoms
Rheumatoid arthritis (RA) is an autoimmune condition where the immune system attacks the lining of the joints. It typically starts in smaller joints, particularly the fingers and wrists, and often affects the same joints on both sides of the body. The swelling in RA feels soft and spongy, and the joints may look puffy or feel warm to the touch.
What sets RA apart from osteoarthritis is its systemic nature. It doesn’t stay in the joints. According to the National Institute of Arthritis and Musculoskeletal and Skin Diseases, RA commonly causes fatigue that goes beyond normal tiredness, occasional low-grade fevers, and loss of appetite. Over time, it can lead to problems in the heart, lungs, blood vessels, eyes, and skin. Firm lumps called rheumatoid nodules can form under the skin near the elbows and hands. Some people develop anemia, dry eyes and mouth, or neck pain.
RA symptoms tend to come in flares, periods where inflammation ramps up and joints become noticeably more painful and swollen, followed by stretches of relative quiet. Early RA can be subtle: vague joint aching, mild stiffness, or just feeling generally unwell. The formal diagnostic process considers how many joints are involved, blood markers of inflammation, specific antibodies, and whether symptoms have lasted at least six weeks.
Gout Symptoms
Gout has one of the most dramatic presentations of any arthritis type. Flares often strike suddenly in the middle of the night, with pain intense enough to wake you from sleep. The affected joint, most classically the base of the big toe, becomes extremely swollen, red, warm, and so tender that even the weight of a bedsheet can feel unbearable.
Gout flares usually hit one joint at a time. The pain peaks within the first 12 to 24 hours and then gradually subsides over days to weeks. Between flares, the joint may feel completely normal. But without treatment, flares tend to become more frequent and can start affecting additional joints like the ankles, knees, wrists, and fingers.
Psoriatic Arthritis Symptoms
Psoriatic arthritis develops in some people who have psoriasis, the skin condition that causes red, scaly patches. Joint symptoms can appear before, after, or at the same time as skin symptoms, which sometimes makes it tricky to identify. It can affect any joint but has a few hallmark features that distinguish it from other types.
One of the most recognizable is dactylitis, a global swelling of an entire finger or toe that gives it a puffy, sausage-like appearance. Unlike the localized joint swelling you see in RA, the entire digit swells from base to tip. Nail changes are another telltale sign: small pits or dents in the nail surface, separation of the nail from the nail bed, or discoloration. Psoriatic arthritis can also cause pain where tendons and ligaments attach to bone, particularly at the Achilles tendon or the bottom of the foot.
Arthritis Symptoms in Children
Arthritis isn’t limited to adults. Juvenile idiopathic arthritis is the most common type in children, and its symptoms can be easy to miss because young children often don’t complain directly about joint pain. Instead, the first sign may be limping, especially in the morning or after a nap. A child might seem clumsier than usual or avoid activities they previously enjoyed.
Swelling tends to show up first in larger joints like the knee. Some children develop high fevers, swollen lymph nodes, or a rash on the trunk that worsens in the evening. Over time, juvenile arthritis can interfere with growth and bone development, potentially causing one limb to grow slightly longer or shorter than the other. Early treatment is important for preventing these complications.
When Symptoms Signal Something Urgent
Most arthritis develops gradually, but one scenario requires immediate attention: septic arthritis, a joint infection. The warning signs are sudden, severe pain in a single joint that comes on fast, along with swelling, warmth, skin discoloration over the joint, and fever. The pain is typically bad enough that you can’t use the joint at all. This is different from a gout flare (though they can look similar) and needs rapid evaluation because infection can damage the joint quickly without treatment.
Patterns Worth Paying Attention To
If you’re trying to figure out whether what you’re feeling could be arthritis, a few patterns are worth tracking. Pain that lasts more than a week, stiffness that’s getting progressively worse, or symptom flares that seem to be increasing in frequency or intensity all warrant a medical evaluation. The same goes for pain severe enough that you’re avoiding your usual activities or sudden difficulty moving a joint that previously worked fine.
Keeping a simple log of when symptoms appear, which joints are involved, how long morning stiffness lasts, and what makes things better or worse gives your doctor useful information. The pattern of joint involvement, the timeline, and the presence or absence of systemic symptoms like fatigue and fever are what help distinguish one type of arthritis from another and point toward the right treatment approach.
