Thank you for your question regarding a sore abdomen one year after a tummy tuck. It is not uncommon for muscle repair to hurt years after a tummy tuck or abdominoplasty. During the standard abdominoplasty, this abdominal muscle is plicated or sutured together. This is done from typhoid to the pubic region. This leads to a nice flat belly for years to come. The trade-off is that occasionally you will have abdominal pain. The abdominal pain can be exacerbated by specific movements, wildly twisting, or bending. In addition, coughing or vomiting can induce abdominal pain. Since your ultrasound did not find a hernia, I do not think further workup is needed. You will have to become accustomed to the periodic pain. If the pain becomes unbearable, you may consult your plastic surgeon. It is possible that the internal muscle sutures must be released or loosened. Thank you for your question regarding continued abdominal pain one year after a tummy tuck.
