The phrase arthritis is usually associated with pain and discomfort. This is caused by swelling in multiple joints, as well as the stiffness that is also common with arthritis. However, it’s important to know that when we use this word, it doesn’t refer to just one singular problem. The word ‘arthritis’ refers to multiple conditions. This is no surprise as millions of people suffer from it across the US. It is also not just reserved for the older generations; both children and even some infants can develop arthritis.
