I have a 10cm mass. I was told after the seeds were implanted that I still need a liver resection or the mass will collapse. They did NOT tell me this prior to the seed implementation. They said that the seeds will prevent it from bleeding out or getting bigger. It was an entire month to recover. The instant the 1M seeds were implanted I felt instant back pain as I was partially sedated. The second day I felt like I was having a heart attack. I had wrap around chest and back pain. The nurse came into my room and he stated, "Your not in here for that!" And he leaves the room. I honestly thought I was having a heart attack! I called the main number of the hospital and give them my room number not knowing if I was dying. They said call your nurse. I said, "I tried!"....he walked away not even checking my vitals. The switchboard transferred me back up to the floor and they sent me a different nurse. Next time that happens I'm calling 911!
