(CNN) -- Arthritis in the United States is more common than previously thought, according to new research published by the Arthritis & Rheumatology medical journal- especially in people 65 years of age and younger.
Its findings are based on data from more than 33,000 participants in the 2015 National Health Interview survey which found that more than 19% of men and 16% of women age, 18 to 64 years old, reported some joint symptoms without a doctor diagnosis.
The Centers for Disease Control and Prevention says almost 55 million American adults have had a doctor diagnose them with painful joint inflammation and stiffness.
And of the current cases of arthritis, the majority are people under the age of 65.
The Arthritis Foundation suggests these tips for managing pain associated with arthritis:
-Take any medication as prescribed by the doctor.
-Manage your weight and stay active. Water aerobics, yoga, and walking can help reduce joint pain and improve flexibility.
