a few hours ago I went to see my dr and found out my port has flipped and will be having the correction done in a few weeks, he said that 1 in 20 people can have this occur and they aren't certain of why it happens, could be exercise, lifting something heavy, a stitch breaks, many things. Super disappointing, I'm 2 years post surgery and now this!! He said its an easy fix and he hasn't ever had someone have this issue twice (lets hope!)
