When you think of “arthritis,” what comes to mind? For many, it’s a fuzzy mental picture. For millions of Americans, however, the image of arthritis is in painful focus.

The term arthritis refers to more than 100 different types of related conditions. Rheumatoid arthritis (RA), for instance, is a form of inflammatory arthritis and affects more than 1.3 million people in the United States, roughly 75 percent of whom are women.

RA is also often referred to as an “invisible” chronic illness, as its most common signs — inflammation, joint stiffness, and internal pain — are difficult if not impossible to see with the naked eye. And the nature of flare-ups means that RA can range from being a minor nuisance one day to debilitating the next. People who have invisible chronic illnesses like RA can experience stigma or encounter discrimination from those who don’t believe or understand they are ill. For many, this stigma is a barrier to talking about it, and can negatively affect how they feel about themselves.

Sharing personal experiences and dispelling myths promotes understanding and can help reduce stigma and discrimination. Here are the best Twitter accounts to follow for news, stories, tips, and support by and for the RA community.

On Twitter, the American College of Rheumatology promotes awareness not only of rheumatic disease but also of the field of rheumatology. Look to this account for information on rheumatology conferences, resources, and tools for getting involved in the movement to advance rheumatology.
