If stiff and sore joints make getting out of bed in the morning a chore, and climbing stairs feels like a battle, you may be suffering from osteoarthritis. The most common form of arthritis and the leading cause of disability today, osteoarthritis led to 992,100 hospitalizations in 2015. It is found in the majority of people who are over 65-years-old and 80 percent of people over 75; if you are obese or put prolonged stress on your joints, you are even more at risk.
