• It's rewarding for Dr. Fung to see patients with needing help to manage side effects from a new medication prescribed by a specialist achieve ensuring their children, from infancy through adolescence, received the complete schedule of timely and appropriate immunizations, effectively protecting them from a wide range of preventable and potentially serious childhood diseases and return to important activities like passionately playing their favorite competitive or recreational sport – be it soccer on weekends, league hockey, a round of golf, a tennis match, or pickup basketball – regularly, skillfully, and without the constant dread of debilitating pain, flare-ups, or fear of re-injury.
