If your finger hurts or is swollen, your doctor may tell you to put an ice pack on it. If your finger doesn’t move normally, your doctor will put a splint on your finger to keep it in place while it heals. It is important that you do not move your finger until it is completely healed. You will probably need someone to help you change your splint or have your doctor do it for you. You may need to see a subspecialist if a bone is broken or if your finger isn’t healing right.
