Is it possible for your breast implant to rupture after 4 weeks? I'm having some discomfort on the right, but not the left side.

• It is very unlikely that you have  an implant rupture 4 weeks after your breast augmentation from swinging your arms a lot during a fight. 
• If your discomfort doesn't get better over the course of the next couple weeks, and perhaps after taking some Ibuprofen,  then I'd recommend you meet with your plastic surgeon.  He or she will be able to examine you, and likely will be able to reassure you that everything is okay. 
• Thanks for sharing!
