Arthritis refers to joint inflammation conditions that cause pain, stiffness, and reduced mobility. The most common forms include osteoarthritis from wear and tear, and rheumatoid arthritis from autoimmune responses. Treatment combines medication, physical therapy, and lifestyle changes to manage symptoms and maintain joint function.
Arthritis describes inflammatory joint conditions that affect millions worldwide. The term encompasses several disorders where joints become painful, swollen, and difficult to move. While you may encounter this spelling online, it typically refers to what medical professionals call arthritis.
Your joints connect bones and allow movement. When inflammation develops in these areas, everyday activities like walking, typing, or holding objects become challenging. The condition can strike at any age, though risk increases after 40.
Two factors drive most joint problems: mechanical wear from years of use and immune system dysfunction that attacks healthy tissue. Both create inflammation that damages cartilage—the smooth cushioning between bones.
This form develops when cartilage gradually breaks down. Think of it like tire treads wearing smooth after thousands of miles. Your knees, hips, hands, and spine face the highest risk because they handle constant stress.
Symptoms appear slowly over months or years. You might notice morning stiffness that improves after moving around. Pain typically worsens with activity and eases with rest. Small bone spurs may form as your body tries to repair damage, sometimes creating visible bumps on finger joints.
Weight-bearing joints suffer most. A 150-pound person places 450 pounds of force on their knees with each step. Over the decades, this pressure wears away protective cartilage.
Your immune system mistakenly identifies joint tissue as foreign and attacks it. This creates persistent inflammation that can damage joints quickly if untreated.
Unlike osteoarthritis, rheumatoid arthritis often affects the same joints on both sides of your body. If your right wrist hurts, your left probably does too. Morning stiffness lasts longer—often an hour or more. You might also feel tired, run a low fever, or lose your appetite.
Women develop this condition three times more often than men. It typically appears between ages 30 and 60, though children can also be affected.
Joint pain is the hallmark symptom, but it varies in character. Some describe it as dull and aching, others as sharp and burning. The intensity fluctuates throughout the day and worsens during flare-ups.
Stiffness makes joints feel tight and difficult to move, especially after sitting still. Your fingers might feel stiff in the morning or after typing for extended periods. This usually improves with gentle movement.
Swelling occurs when excess fluid builds up around inflamed joints. The area may appear puffy and feel warm to the touch. Severe swelling can stretch the skin, making it look shiny.
Reduced range of motion develops as inflammation and damage progress. You might struggle to fully bend your knee, raise your arm overhead, or make a tight fist. This limitation affects your ability to perform routine tasks.
Some people notice grinding or clicking sounds when moving affected joints. This happens when roughened cartilage surfaces rub together, or when bone touches bone after cartilage wears away completely.
Age remains the strongest predictor. After 65, more than half of adults show X-ray evidence of joint changes, though not everyone experiences symptoms.
Genetics influences susceptibility. Having a parent or sibling with joint problems increases your odds. Researchers have identified multiple genes that affect cartilage structure and immune function.
Previous injuries raise long-term risk. Athletes who tore knee ligaments face higher rates of arthritis in that joint years later. The initial trauma disrupts normal mechanics and accelerates wear.
Excess weight adds mechanical stress. Each pound of body weight translates to three pounds of pressure on the knees during walking. Losing 10 pounds removes 30 pounds of force from these joints with every step.
Certain occupations increase exposure. Construction workers, miners, and professional athletes develop joint problems at higher rates than office workers. Repetitive motions and heavy lifting contribute to cartilage breakdown.
Infections occasionally trigger joint inflammation. Lyme disease, hepatitis, and some bacterial infections can cause temporary or chronic joint problems.
Your doctor starts with questions about your symptoms. When did pain begin? Which joints hurt? Does anything make it better or worse? Do family members have similar issues?
Physical examination reveals visible signs. The doctor checks for swelling, warmth, redness, and tenderness. They assess how far you can move each joint and whether movement produces grinding sensations.
Blood tests detect inflammation markers. Elevated C-reactive protein or erythrocyte sedimentation rate indicates active inflammation. Rheumatoid factor and anti-CCP antibodies point specifically to autoimmune arthritis.
X-rays show structural damage. They reveal narrowed joint spaces where cartilage has thinned, bone spurs, and changes in bone density. Early arthritis might not appear on X-rays.
MRI scans provide detailed images of soft tissues. They show cartilage damage, inflamed joint linings, and fluid buildup that X-rays miss. Doctors order MRIs when the diagnosis remains unclear or before surgery.
Joint fluid analysis helps in specific cases. Your doctor uses a needle to withdraw fluid from swollen joints. Lab testing can identify crystals that cause gout or signs of infection.
Pain relievers form the first line of defense. Acetaminophen (Tylenol) works for mild pain without addressing inflammation. NSAIDs like ibuprofen or naproxen reduce both pain and swelling, but can irritate the stomach with long-term use.
Physical therapy strengthens muscles around affected joints. Stronger muscles provide better support and absorb shock that would otherwise damage cartilage. A therapist designs exercises matched to your specific limitations and goals.
Corticosteroid injections deliver powerful anti-inflammatory medication directly into painful joints. Effects last weeks to months. Doctors limit injections to 3-4 per year per joint because repeated use can weaken tendons.
Disease-modifying drugs slow autoimmune arthritis progression. Methotrexate, hydroxychloroquine, and biologics change how your immune system functions. These require regular monitoring but can prevent permanent joint damage.
Surgery becomes necessary when conservative treatments fail. Joint replacement swaps damaged hips or knees with artificial implants. Arthroscopy removes loose cartilage fragments and repairs torn tissue through small incisions.
Heat and ice provide simple relief. Warm baths or heating pads loosen stiff joints before activity. Ice packs reduce swelling and numb pain after overuse.
Maintain a healthy weight through balanced nutrition. Focus on whole foods: vegetables, fruits, lean proteins, and whole grains. Fatty fish like salmon provide omega-3 fatty acids that fight inflammation. Limit processed foods high in sugar and unhealthy fats.
Exercise regularly but choose low-impact activities. Swimming lets you move without stressing joints. Cycling builds leg strength without pounding knees. Yoga improves flexibility and balance. Start slowly and gradually increase duration.
Protect joints during daily tasks. Use larger, stronger joints when possible—push doors open with your hip instead of your hand. Avoid positions that strain fingers, like tightly gripping small objects. Take breaks during repetitive activities.
Listen to your body’s signals. Some discomfort during activity is normal, but sharp pain means stop. Rest after flare-ups and gradually return to normal activity as symptoms improve.
Stay hydrated. Water helps maintain the fluid that cushions joints. Aim for 8 glasses daily, more if you exercise heavily or live in hot climates.
Consider assistive devices when needed. Jar openers, buttoning aids, and ergonomic tools reduce strain on hand joints. Canes or walkers decrease the load on hips and knees.
Seek medical attention if joint pain persists beyond three days without improvement. Early diagnosis and treatment prevent long-term damage.
Watch for red flag symptoms: sudden, severe pain; joints that are hot, red, and swollen; inability to use the joint; pain accompanied by fever; or rapid swelling.
Schedule an appointment if stiffness lasts more than 30 minutes after waking. This suggests inflammatory arthritis that needs specific treatment.
Don’t ignore increasing limitations. If you’re modifying daily activities to avoid pain, or if pain disrupts sleep, professional help can restore function and quality of life.
Joint inflammation is manageable with the right approach. Combining medical treatment, physical therapy, and lifestyle modifications helps most people maintain active, fulfilling lives despite their diagnosis. Early intervention produces the best outcomes, so don’t wait to address persistent joint pain.
