Hi, I recently coughed up <i>a lot</i> of blood, and it was discovered that the cause for this was a bleeding vessel. Since reading previous posts on pulmozyne, I wonder if the pulmozyme caused it? The posts stated that if pulmozyme is focused on one part of your lung, it will cause that particular site to bleed, but woud that include a vessel? I had been getting more aggressive with my treatments before the incident happened. Any thoughts on this?
