Is it possible to feel the lap band port after significant weight loss?

I've lost 145 pounds since I had the surgery, and I not only feel the port, but if I'm sidelying it's as if I feel the port move or push into me. It doesn't hurt, but it's not comfortable. I had it checked to see if it's slipped about 8 mo ago and it hadn't, but I've lost more weight since then (30 pounds). Is this a normal sensation considering my weight loss? Or should I have it checked again? The last dr deflated it & we are planning on removing it when my schedule allows for surgery.
