A heavy snow fall. I step out and shovel the snow off the driveway and my car. Within a few hours, I am having difficulty breathing; my heart is beating rapidly. At Kaiser, Dr. Sing takes chest X-rays, prescribes an inhaler and a week long course of Prednisone. He suggests I begin seeing a pulmonologist, Dr. Ronald Klayton to follow up on the Sarcoidosis symptoms.
