My daughter had one after my history was given to her pulm. and the cough would just not go away. Arrived in the morning; reassured by my daughter's pulm. Versed for my daughter, which makes them forget the entire experience, as that is what Versed does, and exploration made, with samples taken. A little swelling found in the airways, and results such as increased lipids noted in the airways. It can be helpful. My daughter had very little IGE or IGM when it came to allergie testing when an infant, and then older. (They were seeking the allergy asthma link). No real problems after.
