Encapsulated implant and pain
At this point, I would recommend that you have surgery to correct both problems. Your capsular contracture will probably not improve with more non-operative therapy. Since it sounds like you need implant replacement in the other breast, I would recommend that you have a capsulectomy or capsulotomy with implant exchange of both implants. Reusing the implant in the encapsulated breast has a higher rate of recurrence of capsular contracture than replacing the implant.
