If your implants become tight, one symptom could be increased pain when you move your arms or chest. If this persists even after trying stretching techniques, it may be time to have the implants removed and replaced with a new set. If you experience chronic constipation, this can also make your implants tighter as the contents of your intestines push against them. In rare cases, breast augmentation can also lead to an accumulation of fluid beneath the skin on the chest wall (superficial panniculitis), which can cause discomfort and pressure. Seek medical attention if any of these symptoms persist for more than two weeks.
