I have difficulty breathing around bed time and through the night. I was given an inhaler which does relieve my breathing but doesn’t identify the cause. I’m active 27 year old and partake in running etc without the problem and tests don’t indicate athsma. I seem to always swallow because I feel a lump /mucus in my throat and clear my throat during the day and more at night. I’ve also had a scan on my chest nothing was shown. It’s getting frustrating and I’m concerned.
