What is Arthritis?
Arthritis is a broad term for conditions that cause inflammation and pain in the joints. With over 100 different types, the most common are osteoarthritis (OA, caused by cartilage breakdown) and rheumatoid arthritis (RA, an autoimmune attack on the joint lining). It affects over 350 million people worldwide and is a leading cause of disability. OA pain is primarily nociceptive — driven by activation of peripheral TRP nociceptors from mechanical stress — while RA involves chronic inflammatory mediator release, creating an 'inflammatory soup' that lowers pain thresholds and causes both allodynia (pain from normally painless touch) and hyperalgesia (amplified pain response).
Arthritis affects over 350 million people worldwide. In the US alone, 54 million adults have been diagnosed with some form of arthritis, and the number is projected to reach 78 million by 2040.
Common Symptoms
- Joint pain, tenderness, and stiffness
- Swelling and redness around affected joints
- Decreased range of motion
- Morning stiffness lasting 30+ minutes
- Fatigue and general malaise
- Joint deformity in advanced cases
Common Causes
- Cartilage breakdown from age and wear (osteoarthritis)
- Autoimmune attack on joint lining (rheumatoid arthritis)
- Genetic predisposition
- Previous joint injuries
- Obesity adding stress to weight-bearing joints
- Infections that trigger reactive arthritis

Frequently Asked Questions
Can arthritis be reversed?
Osteoarthritis cartilage damage usually cannot be fully reversed with self-care. Some regenerative procedures, including Platelet-Rich Plasma (PRP), are being studied and may help selected people with pain or function for limited periods, but results vary and stem cell interventions for arthritis remain investigational. Exercise, weight management, and clinician-guided treatment remain the best-supported foundation.
What foods help with arthritis?
Anti-inflammatory foods like fatty fish (salmon, sardines), leafy greens, berries, olive oil, nuts, turmeric, and ginger may support an overall arthritis plan. Some compounds affect inflammatory pathways, but they are not substitutes for prescribed treatment and can still interact with medications or cause side effects.
Is exercise good for arthritis?
In most cases, yes. Regular low-impact exercise like swimming, cycling, and walking can strengthen muscles around joints, maintain flexibility, and reduce pain. Arthritis organizations commonly point to about 150 minutes of moderate activity per week as a useful goal, adjusted to symptoms and medical guidance.
What is PRP therapy for arthritis?
Platelet-Rich Plasma therapy involves drawing your blood, concentrating the platelets, and injecting the plasma into an affected joint or tendon. Some studies suggest PRP may improve pain and function for certain musculoskeletal conditions, but protocols vary, insurance coverage is limited, and it should be discussed with a qualified clinician.
