Stephanie, thank you for that reassurance. I cannot see how it could make a difference either really, but thought that others may know a bit more about it and so I thought I'd throw the question out there.
I am thinking of getting the test re-done, but it will have to be done privately and comes with a hefty price tag! But I need answers as to what's causing my problems, I cannot go on feeling so ill forever. I am also thinking of asking for a referral to an ENT specialist.
All the best.
