2-3 months ago, I experienced an indigestion feeling in my chest and had a bit of a panic attack(?) gasping for air. I went to A&E and they said it was because of a possible hayfever attack (Not asthma). I've had hayfever since forever and I've never had an attack previously or after this incident. I'm perfectly healthy. I've been told this may hinder my chances? What do you guys think?
