I also get these symptoms, the only thing what i can see it might be, is although i dont have hayfever, either a higher pollen count could have some minor effects on the chest, or dust, and my sister has recently moved bck in from university, along with all of her possessions, and it seems to be in the room her **** is in that i can start getting a bit wheezy..
im not a Pro or anything but its just my $0.02
Thanks
I too am having symptoms like you. Is there anyone out there who can help? Sometimes when this happens, I feel like my heart is beating too fast.
