After one week of having Walter at home he was due for a doctors visit. It was a regular check up however, when Walter was in the hospital they did something called a spinal tap. The spinal tap left a hematoma in the middle of Walters back. This is when things took a turn in Walters life. Once the hematoma was witnessed Walter was sent to Children’s Hospital in Minneapolis MN. They diagnosed almost immediately with Hemophilia A.
