Knee arthritis is a common issue among the elderly population, with over 20 million people experiencing it every year in America alone. The main symptom of this condition is swelling around one’s knees which increases over time as the disease worsens. A person may also experience pain or stiffness when trying to move their knee joint, but these are not necessary for diagnosis from your doctor. There are four different types of knee arthritis: osteoarthritis, rheumatoid arthritis, gouty attacks, and septic bursitis. To avoid all forms of this ailment, you should maintain an active lifestyle that focuses on healthful eating habits while staying fit physically at least three times per week. To prevent it from worsening, you should also try to work with your doctor on a treatment plan to reduce pain and swelling while allowing for normal movement. Also, make sure to avoid putting any weight on your knees if they hurt. Click here to read about Knee Arthritis: Prevention, Causes, and Symptoms.
