Hi doctors, I am suffering from breathing issue and always feeling like issue in upper respiratory system and tightness of chest. I suffered a lot when I have coughing and sneezing. I feel like something is there in my neck and couldn't breath properly. I went to pulmonologist and he given some medicine and airz to inhale in night. When I am taking this in the night I feel like suffocation and shortness of breath and I couldn't even sleep in night. Sometimes my heartbeat goes beyond 100-150. So I stop taking that medicine currently. I took 2 days and both days I suffered a lot. Can I take airz in day time? Please suggest doctors what should I do to resolve this permanently. Due to breathing issue sometimes I suffer from anxiety. Please help me out.
