I had sudden onset of pain (level 6) exacerbated by movement (level 10) on Tuesday evening. It feels like I broke the plate again. I was in a car accident in July 1997 that broke my left ulna. Two days after I was released by my orthopedic doctor, I broke the plate while helping a friend move a book shelf. He replaced the plate in February 1998. Now it is December 2009. It feels like I broke the plate again. Hoping it something else. Any ideas? Thank you.
