Hello,
To answer your question quickly, you can stay like this the rest of your life; it won't harm you.
However, I would like to address a few things for the purpose of educating women who are reading your post. Breast augmentation surgery is not risk free, and aside from potential rippling of your implants, capsular contracture is the most frequent complication. These are things that should have been discussed with you prior to your surgery, along with the financial obligations associated with re-operation. I don't know who your doctor was, or whether he/she is qualified to perform breast surgery, but having capsular contracture does not mean that your doctor did something wrong, nor does paying more money for a repair imply that there is fowl play.
The best thing anyone can do once they've decided to go forward with surgery is pick their surgeon carefully. Make sure that the surgeon is certified by the ABPS, and is also a member of the ASAPS, indicating proficiency in aesthetic plastic surgery. LISTEN to the doctor about the risks and benefits of the surgery. Know what the doctor's policy is regarding revision surgery, and the financial obligations of such. Listen to the doctor's recommendation regarding sizing of your breast implants. If he is a cutting edge surgeon that provides the best care possible based on data, he will tell you what implant is appropriate for you, and that going bigger will increase your risk of all complications, including capsular contracture. Finally, don't pick the surgeon based on the lowest cost. It is not a true cost comparison, because you are most likely not getting the same thing (breast augmentation) when going from doctor to doctor. The cost of having surgery correctly in a accredited surgery center, using the best supplies, the cost of office visits, and the surgeons training, skill, and experience make all the difference.
