Today much better. But I had 5 days in hell after the surgery. Just pure pain on my left ribs (you're afraid to cough, but you must in order to spit out the blood from the lungs, can't laugh, can't breath deeply -> because it all expands chest and so the wounds on the ribs are affected) all followed by a fever, total energy loss and throat hurted due to that breathing tube. Sleeping was impossible, since the rib cage gets squashed and breathing becomes even harder. I had some cables in my body to drain out the blood and other fluids after the surgery. Removing that thing was horrific.
Now I have to wait for biopsy results and see what kind of cancer it is in order to start the treatment, but I know it is squeezing heart's vessel (that's the reason I can barely walk up the stairs) and some tiny portion of the lungs is also affected by it.
All in all, I have faith that I'll get through it. It's the only option you got really and in the end as painful as it is, a great lesson and life learner.
