Hello cpdmom3, thank you for your question regarding the knot under your ribcage post-tummy tuck and breast lift. Given your history and recent surgery, it's understandable to be concerned about new and unusual sensations. At 12 days post-op, experiencing some discomfort and noticing changes in your body is not uncommon. The knot you describe could be due to several factors. Firstly, post-surgical swelling and fluid accumulation are common after major surgeries like a tummy tuck and mastopexy with augmentation. This could manifest as a knot or lump under your ribcage. Additionally, sometimes blood (hematoma) or fluid (seroma) can accumulate under the skin, leading to a palpable lump. These usually resolve on their own but sometimes require drainage. The healing process involves the formation of scar tissue, which can feel like a knot under the skin. This can sometimes cause discomfort, especially with movement or coughing. Given your past history with hernias, it is possible, though less likely, that you could have developed another hernia. However, it is essential to differentiate between post-surgical healing and a hernia, which would require a physical examination by your surgeon. To address this issue, it is crucial to have your plastic surgeon evaluate the knot to determine its cause and appropriate treatment. They might recommend imaging studies like an ultrasound or CT scan if a hernia is suspected. In the meantime, avoid activities that may strain your abdomen, including heavy lifting and vigorous exercise, until you have been evaluated. Over-the-counter pain relievers may help with discomfort, but ensure you discuss this with your surgeon first. Your surgeon will provide the most accurate diagnosis and treatment plan based on a physical examination and your medical history. It's essential to follow their advice and attend all follow-up appointments to ensure proper healing and address any concerns promptly. Good luck, and I hope this helps address your concerns regarding the knot under your ribcage. Sincerely, J. Timothy Katzen, MD, FASMBS, FICS
