Port dislocation

So, I've been have some burning and stinging feelings around my port area for the past few days but kinda shrugged it off as typical post op port pain(I'm almost 6 weeks post op). But then tonight I was touching my port area and felt this hard lump sticking out from my incision. I checked it out and I can see the white of the port really sticking out and it appears to me that more port has at least detached partially. The skin hasn't broken... But my skin there is super thin. I'm hoping it doesn't pop through the skin before I see my surgeon on Monday. I called my surgeon tonight and he wants to see me first thing Monday.

Anyway, my question is have any of you had this problem or heard of this problem? Is it somewhat common? To repair it will I need another surgery? It's somewhat painful so I'm assuming it can't just stay like this.

Thanks for your input. I'm a little concerned about this.
