Signs That Breast Implants Are Encapsulated?

The firm, hard breasts that you are describing sounds like capsular contracture. This is scar tissue that can form around the implants and cause them to become more firm and distorted. If they look unnatural and are uncomfortable, you may need surgery to remove the capsules of scar tissue. It is usually recommended to also exchange the implants and place new implants under the muscle. Capsular contracture is less common with implants placed under the chest muscle.

The implants need to be massaged to keep them soft.  In the early postoperative period, it is critical to massage the implants while they are settling.  Encapsulation is characterized by hard, immobile breast implants.

Thank you for your question.
Capsular contracture to develop take at least few months so is not usual for the patients to feel that there was something not right since the beginning. 
Generally speaking the first sign of capsular contracture is a progressive hardening that can progress causing pain and change in shape and position of the implants.
Kind Regards

There is grading system for capsular contracture from 1 to 4. Many women experience some  firmness but it is often not noticeable enough to be bothersome. A higher grade contracture (3 or 4) is associated with significant pain with or without visible deformity.It seems that you may have a higher grade conditon. Unfortunately capsular contracture remains a bit of mystery and occurs in 3-10% of women with breast implants.Although there are a few non-surgical treatments as with oral medications and external ultrasound, sometimes reoperation is indicated with implant replacement into a new pocket and other manuevers. Unfortunately, once a woman develops capsular contracture it can reoccur even after surgery.You should follow up with your plastic surgeon for an evaluation. 

It is possible that you may have a capsular contracture, but it is also possible that your implants may have been overfilled.  The only way to really discern what is going on in your specific case would be to consult with a board certified plastic surgeon for an evaluation.  I may recommend that you bring along an operative note from your prior surgery, as this could help your doctor better crack the case.  A capsular contracture is the over-development of scar tissue around your breast implants.  While capsular contracture rates are fairly low, it can occur as this scar tissue begins to constrict or tighten around your breast implants.  This can cause the breasts to harden and distort in appearance/shape, which often leads to pain and discomfort for the patient.  The only way to address this is to perform a capsulectomy, where all capsule or scar tissue is removed from the breast pocket, and exchange your implants for new ones.  I would recommend thinking about silicone gel implants as an alternative to the saline implants, as they tend to feel and look much more natural than saline implants do.
