Pulmonary Embolism Support Group
By far the most common form of pulmonary embolism is a thromboembolism, which occurs when a blood clot, generally a venous thrombus, becomes dislodged from its site of formation and embolizes to the arterial blood supply of one of the lungs. Symptoms may include difficulty breathing, pain during breathing, and more rarely circulatory instability and death.
Personally, I felt pretty awful 3 months after diagnosis. There was some improvement after that although things recurred after 7-8 months so back to stage 1.
At three months, I was still very anxious, had aches and pains along my spine and breastbone, got SOB (short of breath) very easily, and had days where I had exhaustion so extreme that I really couldn't do anything. All that continued to improve. I saw drastic improvements up until about 11 months out and continued to see more minor improvements even beyond that. I'm at four and a half years out at this point and I've been back to normal for quite a while now.
It's hard to say exactly how your path will go, but I would definitely expect to continue to see improvement past three months.
I think I understand what you mean about the lungs feeling heavy. The first 6 weeks out, I felt like my lungs were full of cotton. They just seemed like they were "full", and I would get SOB, just walking across the room.
Like rosiethecat said, focusing on the good days is so helpful. I've had some ups and downs, especially as I feel better, and start doing a lot, and then find myself exhausted, and needing a "rest" day. Reminding myself that I'm still healing, helps me accepting of those times. Thinking back to where I was a few months ago , and where I am now, I truly feel very grateful.
Four months out and I think the only problems that remain for me are swelling (in the leg that had my DVT) and many coumadin side effect issues. Running is harder in high humidity and bitter cold but I think that has always been a problem.
Good luck!
