On time and Dr zawacki treated me with great respect

Dr Zawacki made me feel very confident that my symptoms do not pertain to a serious illness by explaining the medical characteristics of my situation vs others. Gave me confidence that my discomfort can be resolved changing the schedule of my daily routine, while watching future lab results!
