Bubble sensation in breast — sensation when I bend

I recently posted a question asking about feeling a bubble-like feeing when I bend down. I believe I worded it incorrectly. I also am not sure how long ago I had implants...between six and eight years ago. My question is that when I bend over, I have a sensation in my breast that is like a bubble feeling. It is not by my hand; it's not tactile. It's a sensation within. The bone under the breast hurts as well. Is there a potential problem with the breast or could it be normal?
