It's going, slowly.
I'm sure this is just triggered by a lung infection. I always used to throw these things off very very quickly. Not any more.
The 'fingernail' test shows I'm not short of oxygen, but I am getting very dizzy if I walk fast. Had to sit down last night for 5min or so, the whole world was shaking. I suspect my blood pressure has shot through the roof as I'm getting constant flooding nosebleeds today.
I'm going to see the doc on Mon.
