Is it normal to feel fluid when touching the top part of your breast after a BA?

Thanks for sharing your concerns with us. In my practice, after performing a Breast Augmentation I recommend to my patients to limit the movement of the arms for two weeks. After that, you can move your arms taking care and always with common sense. In this regard, it's not advisable to carry heavy weights to prevent the implant out of position, and allow the formation of the physiological capsule around the implant, also to avoid pain and breast swelling.I recommend you to talk with your plastic surgeon about what you are feelling and be evaluated, also follow his advices.Respectfully, Dr. Emmanuel Mallol.-

You may feel the sensation of fluid, swelling, squeaking, sloshing, and subcutaneous air (feels like Rice Krispies!) in the first 2-4 weeks after breast augmentation.  Virtually all of this resolves.

Many patients hear or feel fluid around their implants early after surgery. In fact, a few teaspoons may be present for several weeks before being absorbed. Concerning fluid collections tend to show up as significant asymmetry or deformity in the shape of the breast.Since the gel tends to act more like a solid than a liquid, it is unlikely that the feeling is due to leaking gel. It's easy to freak yourself out after surgery. As long as you follow up with your doctor regularly and follow your restrictions, it is very unlikely that anything will go wrong. 

In the early stages of your healing, your breasts will feel funny, you may think you feel fluid or air moving around.  This will settle with time.  If you develop a fluid collection after your breasts have fully healed you should let your surgeon know.  A late fluid collection may need to be drained as it probably won't resolve on its own

If you had your augmentation recently, it is probably related to your recovery. If you had your surgery a while ago, I would definitely recommend that you contact your surgeon. Regardless, I don't think it's an implant link since, in general, most patients can't actually feel an implant leak. Best, Dr. Nazarian
