During a physical exam, a doctor will check the patient’s joints for swelling, redness, warmth, and range of motion. If there are issues in any or more of these areas, then this could be indicative of arthritis. There are other tests too, such as blood, urine, and joint fluid tests, X-rays, CT scans, MRIs, and ultrasound. Urgent care clinics like ours can provide X-rays in-house and easily refer patients for other tests if necessary. These clinics also have fully capable doctors who can diagnose arthritis and provide numerous treatments.
