There was no idication that my port had flipped. I do not know why this occurs but would like to know. I had to have my port replaced as a result one year after surgery, and now 2.5 years later, it is flipped again. My doc wants me to have outpatient surgery to get it fixed but am looking into seeing if my insurance covers it. Hopefully it does. I have not had ANY type of discomfort due to its flipping. Hope this helps someone. And if anyone knows why this happens, I'd be inetrested in knowing. Thanks! God luck to All!!!
