That's kinda the exact "sore" that I had, it felt as if the actual "lung" muscles(again.. take it easy on me guys, don't have the lingo down yet

) were sore as if I'd somehow worked em out at the gym. I can handle sore, but the thing that kinda bothered me was the "wet" feeling that accompanied the soreness. Best I can describe it as, is it felt as if my lungs were "sweating"...
Again, I don't believe it's a depth issue as much as a time down at depth issue. I've researched a little on the subject but still don't understand what stretching or exhale dives would do to remedy the situation.
