Is Squishing Noise & Swelling Normal 2 Days Post Breast Augmentation?

The squishing noise and swelling that you are describing 2 days post breast augmentation sounds normal.  Good luck with recovery.

Yes, this can happen.  If some air is trapped in the pocket where the implant is placed, it may gurgle or whistle with motion until it is all absorbed.  This should resolve within 1-2 weeks.

Before the capsule has formed around the breast implant, the pocket in which the implant resides as fluid which the implant can shift as it moves around. This can generate some benign sounds that can be unnerving. Nothing to worry about.

Thank
you for your question. I have included some typical expectations of breast
surgery recovery and signs to watch for following breast augmentation:
Stiffness, swelling
and bruising in the chest region: These are normal experiences as the skin,
muscles and tissue heal. Pain medication and muscle relaxants will help you
cope with any discomfort. Consistent sharp pain should be reported to your
board-certified surgeon.Hypersensitivity of
nipples or lack of sensitivity: This is normal and will gradually resolve over
time.A mild to severe itchy
feeling of the breasts is possible as healing progresses. An antihistamine like
Benadryl can help to alleviate severe, constant itchiness. If the skin becomes
red and hot to the touch, contact your board-certified surgeon
immediately.Asymmetry, the breasts
look different, or heal differently: Breasts may look or feel quite different
from one another in the days following surgery. This is normal. No two breasts
in nature or following surgery are perfectly symmetrical.Discuss returning to
work with your board-certified surgeon, in our office it is typically 3-5
days post-surgery but you may not overexert yourself or do any heavy lifting.You may resume
exercise and your normal routine at six weeks unless your surgeon advises
otherwise.Be sure to follow up with your board-certified plastic surgeon regarding questions or concerns during your recovery. 

What you are describing is quite commonly described after breast surgery.  The sensation of air trapped in the tissues is also commonly described. However, any significant increase in swelling/size would be of concern.

 Best wishes.
