To make the most of your upcoming doctor's appointment, start by gathering your medical records and listing your current medications. Take note of your symptoms and any questions you have. Don't forget to bring your insurance card and identification, and try to arrive a bit early. If your doctor provided specific instructions, be sure to follow them. Consider taking a trusted friend or family member for support during the appointment, and remember to be open and honest with your doctor about any changes in your health or concerns you may have.
