Hi all,
Here is the problem. In the august 2006, after my return from the Tien Shan Mountains (where I had done some climbing to the mountains of height up to 4800 m. (16000 ft.)) I had a spontaneous pneumothorax (collapsed lung) and as a result a surgery on my right lung. Doctors said me that I have to stop backpacking and climbing because low pressure in the mountains could trigger another spontaneous pnemothorax.
Well, I didnāt listen to them and continued to make trips. Everything was fine and I returned to my normal life. In the summer of 2007 I did a three-week backpacking trip and then in winter of 2008 I had a backpacking in a quite cold weather conditions. As a result, I got pneumonia (in the right lung) which then gone. But in the july of 2008 I had collapsed lung again. And again doctors said no physical activity forever.
Three weeks after this event I went to the Ural Mountains and then to the Sayan Mountains in the Siberia where I climbed to the the mountains of height up to 3000 m. (9800 ft.), everything was fine. Three weeks after the return from my trip I felt a sharp pain in the left side of my chest. So another episode of collapsed lung.
I wonder if anyone had the same problem. Is here anybody who were said to forget of backpacking because of health issues but still continues to do it?
I canāt live without it! Iām planning to do a two-week backpacking trip in the Altai Mountains this summer.
Now Iām trying to make all precautions, that is I learned how to do needle chest decompression (in theory) and bought 14g cath to treat tension pneumothorax (but the probability of spontaneous tension pneumothorax too small). BTW all my episodes of collapsed lung were small, so I was able to walk around, and they all happened not in the mountains. The second happened when I was asleep, so it didn't matter whether I was active or not. And the second and the third healed on their own.
But still Iām a bit afraid. Iām not afraid of tension pneumothorax (itās easy to treat), but Iām afraid that would have stop my trip and return back to the civilization. So because of me my companions would have to return too, but I donāt want to spoil the trip.
What would you do if you were me?
