After several collapsed lungs had a chest drain fitted which involved having a metal tube shoved in between the intercostal muscles awake and pushed from a low point upwards between the chest wall and plural lining till it got to the top part, then they sew the metal pipe in and attach it to a pump for 1 week sucking the air out, then they find out it's in the wrong place and start twisting it around which was like sticking a hot poker into your chest, I will never forget the pain, got better for 1 year but then had full open lung surgery to remove the lining of the lung which meant my lung was then glued/stuck to the chest wall, off work for a month and had a numb chest for ten years, held up ever since even after breaking three ribs a few months ago.
