Arthritis, bursitis, and tendinitis are three conditions that share a common culprit: inflammation. When they settle into your joints or other tissues, these conditions can run the gamut from annoying to crippling.

Bursitis

Bursitis is inflammation of the bursae, which are small, fluid-filled sacs that keep the bones, tendons, and muscles around your joints cushioned and thus keep the joints moving smoothly. Bursae are also located between bones and other structures (like muscles and skin) that move against the bone. If a bursa becomes inflamed, generally because of overuse or repetitive strain, that movement becomes painful.

Arthritis

Arthritis is the number one cause of disability in the United States. Although arthritis is quite common in seniors — roughly half of everyone over sixty-five has been diagnosed with it — it's not strictly an old-person's disease. Almost two-thirds of the 46 million Americans with diagnosed arthritis are younger than sixty-five.

Arthritis encompasses more than 100 different conditions, but osteo-arthritis is the most common, typically striking people who put excessive strain on their joints, have had a joint injury (or joint malformation), are overweight, or have a family history of the disease.

Technically speaking, osteoarthritis isn't caused by inflammation; it comes from physical wear and tear. However, because osteoarthritis includes joint pain, swelling, and loss of function — all symptoms of inflammation — it's is generally lumped in with the rest.

Tendinitis

Tendinitis (or tendonitis) is an inflammation in the tendon, which is the fibrous, cord-like material that joins muscle to bone. It's caused by repetitive strain or injury — think tennis elbow and swimmer's shoulder — but it's not reserved for athletes: Painting or shoveling also can trigger it, as can using incorrect posture or neglecting to stretch before activity.

Tendinitis produces pain just outside the affected joint. Adults over forty are more susceptible, because tendons become less flexible and more injury-prone as you age.

Treatment Options

The “itis” conditions are typically treated with OTC or prescription medicines such as NSAIDs. But there are several herbs that can treat pain, stiffness, and inflammation without the side effects.
