I'm feeling some sort of fluid-moving sensation in my left breast since the past two weeks, Should I be worried? (photo)

Thank you very much for your message and including your photograph. I must say that your breast does not look too
swollen in the photograph so it doesn’t look as if there is too much fluid in
the breast.
It would however, be sensible to keep an
eye on the fluid and possibly see your original surgeon who can arrange a scan
of your breast to check if there is any fluid there and if there is it might be
possible to drain it.
I hope the sensation settles down and wish
you the best of luck.

Better yet why not seen your surgeon ASAP to be examined concerning these issues??? I would if I were you.. 

By nine months there should be neither fluid nor air around the implants. What you are feeling may not be either. The implant can move a bit within the pocket and cause this sort of sensationA visit to your surgeon should easily sort this out.All the best. 

At this stage of healing, you should not have fluid or air around your implants.  Contact your Plastic Surgeon to confirm.
