Questions about pleuricy?

As a result of chemotherapy, I developed pleurisy around my heart and lungs. It is extremely painful. I can only walk a few steps, and then I start gasping for air, and I feel like I am dying. I can't take the Naproxen that is usually prescribed, because I am on blood thinners. I am worried about developing pneumonia, because I can't take the anti-inflamatories, and I keep coughing up a bunch of stuff. How long does this condition take to go away? Are there any home remedies I can do to help?
