SixFive, I'll be 34 in October. My mom was a little younger when she died, I think. Sunday night, they started me on an injection blood thinner (stings like hell) and Coumadin. I have another chest x-ray scheduled for Wednesday morning. Hopefully it'll show the clots have dissipated and surgery won't be required! I have not heard anyone mention surgery yet.
I hope you don't have to have surgery. I'm not a great resource on clotting disorders, but I think people are usually diagnosed earlier in their life. My friend was diagnosed when she was in college and has been on Coumadin for years. Her first problem was also a Pulmonary Embolism. Keep us updated, and I hope you recover fast. It sucks being in the hospital, doesn't it?
