If you think you have RA, the first step in your treatment will likely be a visit to your primary care doctor. Your doctor will take your medical history and perform a physical exam. He or she may also ask about any symptoms you may be experiencing. The doctor will also examine your joints for redness and swelling, gently move them to see if they hurt, and check for tenderness. Based on these findings, your doctor may perform blood tests or other imaging tests to help determine if you have RA.
