Breathlessness and associated symptoms:
I had a CT scan on Friday. There are small clots in the blood vessels of my lungs which probably account for most of the recent distress and breathlessness. I was told immediately after the scan - and I also have the medication to start treating it (an anti-coagulant called Clexane, which I take for a couple of weeks. It is injected subcutaneously - which I do myself - pretty straightforward I am glad to say). I go to discuss the longer term treatments (if needed) next week.
I have calmed down a bit after this - but not immediately 'cured'.
