Arthritis is an umbrella term for about 100 degenerative conditions that affect joints, tissues, and the body’s own cells. Within this umbrella term is osteoarthritis, which is by far the most common form of arthritis around. It usually presents with pain, inflammation, and discomfort on a daily basis. This is a condition that is very similar to bursitis and if your osteoarthritis gets out of control, then this could be a symptom of bursitis. Living a physically active lifestyle is one of the most important things one can do for osteoarthritis so taking care of your muscles and joints is of high priority.
