Hello,Thank you for your question. The risk of forming a hematoma is the highest within a few days of your surgery. I advise activity restriction and my patients are instructed to avoid substances which can increase bleeding risks for a time before and after surgery. The pocket is considered to be strong at 6 weeks and most often people can resume regular activities then without risking damage or malposition of the pocket. Capsular contracture is most likely to develop within the first couple of months as well but can, on rare occasions, develop after several months or years.I recommend that you talk with your plastic surgeon about their protocols for minimizing risks so that you can ensure the best, possible outcome.All the best
