My lung doctor is a primary doctor also. He took care of my family for 30 years. My husband went to him yesterday and he told him to find a new doctor because he is retiring. He told my husband he will keep me because of my lung problem. I have been looking for a doctor. In fact I went on line and only picked the 5 star doctors and I chose 30 to 35 and all are not taking new patients or there office is closed. My family is in trouble. The doctor I pick will be for me also. I am in Worcester Massachusetts
