Anyone have experience with blood clots? Doctors have been trying for a month to figure out why I had severe pain in my chest (right lung) for four days straight. Pulmonologist couldn't find anything on MRI and thinks it was either a blood clot that dissolved on its own or some kind of viral infection on the outside of the lung. Same thing last summer but the only symptom was pain and a steroid pack took care of that immediately. This year, not only was there pain but extreme fatigue and it only took 2-3 minutes of work to get me out of breath for hours. I was debating on an OTC Colorado Elk hunt this year as a refresher to elk hunting but had to give up on that idea. I still plan on drawing a tag somewhere next year and I know it seems a little silly to ask questions without an actual diagnosis, but has anyone had to limit how they hunt or maybe where they hunt because of blood clots? I'm only 33 years old so this could potentially be something that bothers me for a long time so I'm just trying to get as much info as possible. I've never had a problem with elevation sickness but I could imagine that any blood and or lung condition could be worse in higher elevations. Any thoughts would be much appreciated. Thanks all.
