I have also posted this question in the Heart Disease Forum. But, given that I am not sure what it is, I thought to post it with this forum as well.
My 19 year old son was diagnosed with NCS. Now, my 16 year old daughter is being sent for a Methacholine challenge test. Not to question the doctor, but it seems to me that my daughter's symptoms are very similiar to my sons. However, her's occur while exercising (playing soccer), as well as, just in the last three years, while having blood work done, dentist work, and severe pain from a cyst rupturing - she has passed out, When she is standing from sitting position, her vision goes dark and her hearing fades. The most recent concerns are her symptoms during soccer practice. Mostly while doing sprints, she has to stop becuase she becomes extremely breathless, heart pounding, very lightheaded, almost blacks out, her hearing fades in and out, she gets dry heaves and feels as though her throat is tightening on her. Not to mention that her hands become tingly. Does all of this sound as though it is exercise induced asthma or are they true/possible signs of NCS?
