Experiencing significant pain in one breast several years after breast augmentation surgery could be concerning and may warrant further evaluation by a healthcare provider. Here are some potential reasons for your symptoms: 1. Capsular contracture: Capsular contracture occurs when the scar tissue (capsule) that naturally forms around the breast implant tightens and contracts, causing the breast to feel firm, distorted, and painful. Severe cases of capsular contracture can lead to significant discomfort and may require corrective surgery. 2. Implant rupture: Although cohesive silicone gel implants are designed to maintain their integrity, rupture can still occur. If an implant ruptures, it may cause pain, changes in breast shape, or asymmetry. Silicone implant rupture may not always be immediately noticeable, but it can lead to inflammation and discomfort over time. 3. Infection: Infections around breast implants, such as capsulitis or implant-related infections, can cause pain, swelling, redness, and warmth in the affected breast. Infections may occur shortly after surgery or years later, and they require prompt medical attention. 4. Implant malposition or displacement: If the breast implant shifts from its original position or becomes malpositioned (e.g., bottoming out, lateral displacement), it can cause discomfort or pain due to pressure on surrounding tissues. 5. Muscle or nerve issues: Pain in the breast could be related to muscular strain, nerve irritation, or other soft tissue problems unrelated to the implant itself. 6. Other potential causes: Other less common causes of breast pain post-breast augmentation surgery include hematoma (blood collection), seroma (fluid accumulation), or unrelated breast conditions such as mastitis or cysts. It's important to consult with a board-certified plastic surgeon if you're experiencing persistent or severe pain in your breast with an implant. They can perform a thorough evaluation, which may include physical examination, imaging studies (such as ultrasound or MRI), and possibly diagnostic tests, to determine the underlying cause of your symptoms and recommend appropriate treatment options. Prompt medical attention is crucial to address any potential complications and ensure the long-term health and well-being of your breast implants.
