Anyone had a Methacholine challenge test?

hi,

I had a pulmo dr. diagnoise me with (twitchy airways) or asthma as most would call it over 25years ago. Since then I have seen a couple asthma-allergy doctors who keep me on my steriod meds and I always keep a rescue inhaler close by. I have always wondered if I have asthma because my symptons are so different than anyone I know that has asthma. I know for sure I have allergies. I'll just get to the point. I have heard there is a test that can test someone to see if they have true asthma. Its called a Methacholine challenge test. I think I have brought it up to my asthma dr. but he never really responds. Has anyone heard of this test or has anyone had this test and DOES it really prove if a person has asthma or not. I am so at my wits end! I would really like to know if I have it, or if its just allergies. I take allergy meds everyday as well as my Alvesco. I never wake up at night with problems, i never wheeze (i know alot of people don't) I don't get SOB, and I don't cough. I just start to feel funny when I feel an attack coming on. I know that sounds strange but I can't put into words exactly what I feel. Then I'll use my neb or do a puff from my xopenex and feel better. But sometimes I wonder if this might be a MIND thing making me feel better. My PFT test are usually good. And when I feel this feeling I check my peak flow meter and its above or in the green zone so i just don't know. Yes, I get scared because i'm afraid not to use my inhaler. Can anyone give me some advise or maybe just comment. Maybe i just hate admitting I have asthma. Exercising is my life and I hate to pre-treat everytime I exercise. My dr. told me to do this. He is a good Asthma dr. and i'm tried of changing.
Thanks everyone

I've heard of the test as being the only definitive test for asthma, but I've never had it done. The allergist didn't do it since they thought I had such strong supportive evidence for asthma that it wasn't needed (family history of allergies, including a sister that went to the hospital with food allergies as a kid, I have allergies, they can induce an attack with allergy injections, I have sinusitis, I have atopic dermatitis, they do spirometry, then give me albuterol and redo it with an improvement in the numbers, I vary between 55-95% of personal best over a year's time meaning the obstruction is reversible, I improve with asthma drugs, etc.) Maybe you could contact a pulmonologist to see if they would do it?
