Arthritis is the swelling and tenderness of one or more of your joints. The main symptoms of arthritis are joint pain and stiffness, which typically worsen with age.

The most common signs and symptoms of arthritis involve the joints. Depending on the type of arthritis you have, your signs and symptoms may include:

• Pain
• Stiffness
• Swelling, Redness
• Decreased range of motion

The two main types of arthritis — osteoarthritis and rheumatoid arthritis — damage joints in different ways.

Osteoarthritis - The most common type of arthritis, involves wear-and-tear damage to your joint‘s cartilage — the hard, slick coating on the ends of bones where they form a joint. This wear and tear can occur over many years, or it can be hastened by a joint injury or infection.

Rheumatoid arthritis - the body‘s immune system attacks the lining of the joint capsule, a tough membrane that encloses all the joint parts. This lining (synovial membrane) becomes inflamed and swollen. The disease process can eventually destroy cartilage and bone within the joint.

• Family history
• Age
• Previous joint injury
• Obesity

Severe arthritis, particularly if it affects your hands or arms, can make it difficult for you to do daily tasks. Arthritis of weight-bearing joints can keep you from walking comfortably or sitting up straight. In some cases, joints may become twisted and deformed.

Arthritis treatment focuses on relieving symptoms and improving joint function. Always consult with your doctor for the best type of treatment.
