In 2005 I had a grapfruit size mass under my left arm and a softball size mass under my left arm. They were surgically removed and pathology said they were begin breast tissue. I had a suddent onset of a knot that start swelling in th eright arm pit, by the next day it had doubled in size pain was horrible. The er doctor said it was an abcess it was lance, to the Dr. suprise not an abcess and not draining. I have also had a suden tonset of sever ful like symptoms with a high white count and I am on my second round of antobiotoics and pain medication. Sonogram showed a mass surrounded by blood> What is this and will it have to be surgically removed. My incision is still open but not draining and I am going down hill rapidly.
