5 years ago my 3 year old jumped on my chest and hit me with her knee right in the xiphoid process
. My dr. did a diagnosis just on physical exam, no treatment. Have always had a lump
from it and slight discomfort. For the past month I have had dramatic changes: constant moderate pain, the lump has tripled in size, great deal of pain when I wear a bra, nasuea all the time, accassional vomiting, I have had no other injury and I have not changed my routine in any way.
