I have had this thing since just after Christmas, and am just getting to the end of it now. I am on my last course of antibiotics, I have had a previous course before; the last test came back as positive and the infection was antibiotic resistant.
Mine started with a tight feeling in my chest, and then pain going through to the left shoulder blade. The cough was dreadful, but that has almost gone now. I had all the other symptoms you mention. I too am doing a sterling job keeping Tena going!
I have never had anything like it before, had colds obviously, but nothing like this and I had the flu jab (obviously the wrong strain!).
Hope you soon feel better.
