It is not unusual for the breasts to feel firmer and appear more rounded after a capsullorhaphy. If your surgeon really modified the pockets internally, then it can take quiet awhile for the breasts to relax and soften up again. This process can take anywhere from 3-6 months. Without examining you, it is impossible to say whether it is the normal healing process, or whether you are developing capsular contracture. If you are not massaging the breasts, then I would call your surgeon's office and ask them if it is ok to aggressively massage them. If you get to 6 months and they have not changed, I would then talk to your surgeon about the next step. I hope this helps.
If you think you are developing capsules, then you should start on a medication called Singulair (generic Montulakast) 10 mg every day for 3 months, Vitamine E 2,000 IU every day for 3 months and start on a vigourous breast implant massage program.
