I have been diagnosed with asthma for years but actually had it for a few without realising that was what it was. Lately I've been seeing the nurse often and have felt well looked after. I have been on a new inhaler for a week. Today I have had trouble breathing. I have used my inhaler twice and haven't felt any relief. I am awaiting an ECG to rule out cardiac issues but can anyone give me any suggestions as to what I can do to feel better before my next appointment. Thank you.
