Q

What are major differences between RA and OA?

A

RA: rapid onset, typically in 20s - 40s. symmetrical joint involvement, polyarticular. joint pain may improve with usage of joint. systemic symptoms include fatigue and malaise.

OA: slow onset, typically in older age. often begins unilaterally and limited to one set of joints. joint pain worsens with usage of joint. no systemic symptoms.
