Thank you for your question! I hope that these answers help in making your decision. It is not uncommon to have the symptoms that you describe, especially in teenagers once her breasts begin to fully develop. It may be that you have juvenile hypertrophy, in which case, your symptoms may worsen and breast continue to grow and droop over time. However, if you are not having any symptoms and desire the procedure to improve the shape, it would be wise to consider this after your breasts have fully developed. At which time, the shaping could be performed more accurately. Once one begins to have the symptoms that you state above, consideration for a surgical procedure to ameliorate your symptoms, assist with self esteem, and allow you to get back to physical activities in your youth should be done. Given your symptoms, you would be an ideal candidate. You must first discuss with your parents and pediatrician, and then consulting with a plastic surgeon for evaluation and examination to assist you in deciding if this would be the right thing for you. Your surgeon will also go over what to expect as well as the risks and benefits of the procedure. Overall, your symptoms should be ameliorated almost immediately and hopefully give you more self confidence and an increased activity level. Your breasts may still continue to grow over the next several years, but it is certainly reasonable to consider this at this age with the issues that you are having. Many surgeons will recommend awaiting until full breast development prior to consideration, but discuss your concerns. I hope that this helps! Good luck with your decision!
