Thank you for your question regarding the fact that you are three weeks post-op from a tummy tuck and that the swelling in your scrotum has gone. However, one of your testicles is very hard and sensitive, and whether you should be worried. Your complaint regarding one testicle being very hard and sensitive is concerning. You must follow up with your plastic surgeon. The pain in your testicle could be due to swelling. However, it could be something more serious, like testicular torsion. Testicular torsion is when the spermatic cord is twisted, and the testicle runs out of blood supply. Testicular torsion is similar to an incarcerated or trapped (non-reducible) hernia. Testicular torsion could also be due to a suture, tension on the spermatic cord, or pinching of the spermatic cord. Therefore, most plastic surgeons suggest you contact your plastic surgeon ASAP. Thank you for your interesting question regarding one testicle being very hard and sensitive three weeks after an abdominal plasty. Or tummy tuck with liposuction. Good luck. I hope I have answered your question regarding the fact that you are three weeks post-op from a tummy tuck, and one of your testicles is very hard and sensitive, and whether you should be worried.
