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?
While cartilage damage from osteoarthritis cannot be fully reversed, emerging regenerative therapies show promise. Platelet-Rich Plasma (PRP) therapy, which concentrates your own growth factors and injects them into the joint, has shown superior intermediate-term (3–6 months) pain and function improvements versus cortisol injections. Mesenchymal stem cell therapies aim to actually regenerate degraded cartilage. In the meantime, exercise, weight management, and anti-inflammatory nutrition remain the gold standard.
What foods help with arthritis?
Anti-inflammatory foods like fatty fish (salmon, sardines), leafy greens, berries, olive oil, nuts, turmeric, and ginger can help reduce joint inflammation. These work by inhibiting inflammatory enzymes (COX-2, LOX) and reducing pro-inflammatory cytokines — the same pathways targeted by pharmaceutical NSAIDs, but without the risks of gastrointestinal bleeding or kidney damage from long-term NSAID use.
Is exercise good for arthritis?
Absolutely. Regular low-impact exercise like swimming, cycling, and walking strengthens muscles around joints, maintains flexibility, and reduces pain. The Arthritis Foundation recommends 150 minutes of moderate activity per week. Biomechanical research also shows that innovative foot-worn devices that create 'controlled micro-instability' can retrain gait patterns and reduce joint loads by physically redistributing destructive mechanical forces.
What is PRP therapy for arthritis?
Platelet-Rich Plasma therapy involves drawing your blood, concentrating the platelets (which contain growth factors and healing proteins), and injecting the plasma into arthritic joints. Meta-analyses show PRP provides superior pain relief compared to corticosteroid injections, especially at 3–6 months. Unlike repeated corticosteroids, which weaken tendon architecture over time, PRP aims to stimulate actual tissue repair.
