Hello sir I'm 25, male For 4-5 days ,I feel like I have to take an extra deep breath, I feel like my chest is not fully filled. Yawning everytime.  I had this problem around 1 year ago for 2-3 days and it got healed by itself.  No pain in the chest area, no record of chest problems, never had problems related to chest , last month xray is fine. No problem while sleeping, no tonsils in my neck . No smoking or drinking, Is it too bad ?? Or it will go away by itself. Please help me 🙏
