Band Erosion

Has anyone had that happen and how did it feel?  I fell on my port back in Sept and I had bruise for a month right in the spot.  It did not hurt but I felt just odd feeling in the area now I feel like a small pull that I feel it doesn't hurt all that  much just a weird feeling and I have had myu band slip a few times so I know what that is like so it's different.  I was just wondering maybe the area is just still healing from my fall. 

Any help would be appreciated!!!

I'll give you my standard answer: when in doubt, always call your surgeon! 

Echoing Bette. But just to add, I can't see how a fall could cause the band to erode into the stomach,
