Thanks to you all for your support
Have just spoken to respiratory nurse - probably not an exacerbation
I had bloods taken for liver function tests ??last week & also a general allergic response test as it was slightly up the year before.
LFT was normal but allergy response was over 1000 (normal is 0-120). So going to have more specific allergy blood tests to try & narrow the allergy down & be prescribed an antihistamine.
So, although that doesn’t help me at this minute in time, I have something that helps me understand why I feel so lousy & hopefully will be feeling more like myself soon. I will keep people posted.
