I am facing breathing issue while i try to sleep, Sometimes miner pain in chest and left arm. I went to Cardiologist, He did ECG, ECO, ETT and wrote a report with all fine things. I feel like something is stuck in my throat kind of a air bubble. He said you feel whistle sound while breathing that time, i said yes sometimes. He gave me Asthma Inhaler. Tonight again it went worse and i used inhaler too but no effect. I feel like shot breath and Its very tough for me to sleep. If you can suggest me any doctor, hospital or medicine or test I will be very thankful. Thanks for this platform I really appreciate.
