Went to GP today to get scripts re-authorised and mention my fingers problem. I had my GP admit that I do have a Heart and Lung Problem at last!
I explained what happens with my finger tips and mentioned critical illness neuropathy and it was not dismissed, however he said that with my problems it has now become more difficult to diagnose which of my problems is causing this and other things. He would expect my ankles to be swollen as well, which they are not but do leave dents when pressed like my fingers? He has said it could be my circulation or my O2 or both because neither are working 100%.
To add to this some tablets that may help the problem may cause me more problems elsewhere I have had some bad reactions to some wonder drugs.
So I am now back to "Live with It"
