Can a capsular contracture seem to suddenly appear overnight? (Photo)

Unlikely that capsular contracture will occur overnight.  Sometimes, injury and bleeding can occur (normally in one breast) and this can lead to capsular contracture.  Definitely go to your board certified plastic surgeon for a physical examination.

Although there are possible other reasons for your breasts to be swollen and firm, it is also possible that this is a manifestation of capsular contracture. Although it is usually a slow progressive event, you may have not noticed the early changes. Other possible causes could be bleeding or trauma to your breast which could have caused firmness and swelling or possibly a muscle injury. Your plastic surgeon will take a good history and with a good exam can give you a better idea. Good luck.

Capsular contracture is insidious and manifests itself over many weeks. However might reach a critical point where the patient first artist to notice it. If your breast indeed did become firm overnight this should be reported to your plastic surgeon fairly quickly as it may suggest a seroma particularly if texturized implants were placed.
