Swelling, pain and firmness years after breast augmentation could be a sign of capsular contracture, a buildup of fluid, an unrelated problem with your breast or another issue. You should schedule an appointment with your plastic surgeon or your primary care doctor to investigate the cause. You may want to start with the plastic surgeon who performed your breast augmentation since your breast implants could be a factor in the symptoms you describe.
A sudden change such as this should be examined in person. I recommend that you contact your Plastic Surgeon. You could also be examined and have imaging done with your primary care doctor in the meantime.
All the best
Thank you for your question. It may be early capsular contracture or any other conditions. You need to be seen by a PS for evaluation.
I would advise you to make an appointment with your plastic surgeon for evaluation. This could be any number of things, most of which are not dangerous but most of which need to be addressed to maintain the good state of your augmentation. This could be a seroma or a hematoma both are collections of fluid around your implant that would need to be drained and evaluated. This could be an early capsular contracture that may require surgical intervention or if caught early may respond to Singulair. It could be something musculoskeletal unrelated to the implant or it could be a cyst or mass in the breast itself. So you see, you need to be evaluated by a plastic surgeon, preferably the one that placed your implants. Best of luck!
