My doctor that gave me my unfill yesterday had a hard time getting into my port she even used a sonogram thing to find it and it was right under the skin but when she went to stick me she couldnt find it she said my port was very loose like mobile..is that normal

I also have a mobile port. I've had two revisions and its once again loose.

My advice if they can still access it let it be! My port revisions were far worse then the surgery!!

My port was sewn into the muscle so it doesn't move. Is that not the common way?

Yes it is.. mine was also sewn in but it has came unattached three times now I have scar tissue there and it wont stay put ..
