My daughter will be 5 months on the 8th of November and we took her to the dr yesterday for a cough she has had for almost 8 weeks. She does weeze and it seems as though she may have asthma or allergies?? However, I was dumbfounded when the dr told me she thought it may be time for the "sweat test" to check for CF. My family is loaded with people who have allergies and my daughters father has terrible asthma and allergies. The dr is a little sensitive to CF because her brother died at 28 of the disease. No one on either side of our famlies has this so I don't understand how it could be possible?? Can someone please help with some info??? Is my dr just over sensitive? I am so scared it's making me sick.
