100+ Types of Arthritis, the definitive list

Arthritis can refer to any medical condition that leads to joint inflammation.

54 million Americans deal with arthritis of some kind. Many of them aren’t necessarily aware they have arthritis, in part because its degenerative effects are progressive, and also because there’s so many different kinds of arthritis to watch out for. In this list we aim to catalog all of the different kinds of arthritis, and give a brief writeups for some of the well over 100 types of this incredibly common, complex, and perplexing family of disorders.
