I Began Feeling Like I Was Getting A Chest Cold

I began feeling like I was getting a chest cold a month ago. I have a hx of asthma but it normally never bothers me. Fot the past month I have had shortnes of breath and use my inhaler every 6 hours. I thought I had a fever/low grade a few times. I fatigue easily. My eyes feel funny alot. Like blurred and just feel funny. Hard to describe. The shortness of breath is concerning and I have been waking at night to use the inhaler. I had a chest xray that was clear. I had bloodwork in the recent past and nothing was abnormal. I do have some nodules on my thyroid that I am do to get scanned again in a few months to see if they grew but blood work (unrelated to this) was normal. At times it feels like my heart is fluttering but I have had my heart checked recently too and all is normal.
