I'm 22 years old and from several days I have an urge to constantly yawn to get the satisfaction of breathing completely. I have to take deep breath oftentimes. I feel better sometimes but most of the time I feel like taking a deep breath. I take Azelastine and fluticasone nasal spray for allergic rhinitis and cod liver oil capsules in the morning. My Ecg is normal. What maybe the problem? Please help. Thank you.
