I've had this condition for more than 10yrs already. It would occur whenever I feel too excited or even for no reason at all, eg, when I'm just sitting down. All of a sudden, I would have this feeling of breathing difficulty for a few seconds and I can feel my limbs going weak. It feels though I'm continuing to breathe but my lungs are not getting enough air, it feels suffocating.
Then, I would try to relax and calm myself down. I'll force myself to breathe harder and get in as much air as possible, drinking warm water also helps a bit.
Usually I can recover in about 10-15mins time, it's not a fatal condition just that I would feel a bit uncomfortable.
May I know what I'm suffering from?
