After 5 days on heparin/erixtra he stayed only on Cumadin, though at a high
INR, and developed symptoms from a larger clot, now on the julgular vein. he was moved back to heparin and then to lovenox. Then it was noticed that some of his lymph nodes were a bit enlarged around neck and lungs (1.8 cm the largest). They did several ct scans, pet scans, mri, and 3 biopsies to try to diagnose. 2 of them, a core and a surgery, werent able to get tissue from the lymph nodes.
