I now have to have a breast reduction because of the increase in my breast size. Its causing me severe back pain.
Thats true that theres nothing you can bye to enlarge your breast. But I have Endometriosis which means I have really painful periods. We tried everything including birth control pills,depo and pain medication. My OB gave me a shot called depo lypo thats not for birth control its only to stop periods. One of the side effects are breast enlargement and its not reversible. I really didn't believe it but I wnt from a high C cup to a triple D in less than 3 months. I had to stop taking it even though it helped my endometriosis and my breast keep growing for another 2 months. Its really expensive and the pharmacy has to order it and you take it to your Dr for them to mix it and give it to you. Not sure if this helps but just FYI.
None. If your breasts are done growing, the only way you'll see them get larger is to put on weight or get surgery.
