I'm sorry to hear about your experience with PDO threads and the complication you are facing. It's important to prioritize your safety and well-being, and I hope the following information can help guide you in making an informed decision. If one of the threads has made its way out of your nose on the columella, it's important to have it addressed as soon as possible to avoid any potential complications or infections. Pulling the thread out may be a viable option, but it's important to have it done by a qualified dermatologist or plastic surgeon to minimize any risks. If you are uncomfortable returning to the place where you had the original procedure done, seeking a second opinion from a reputable provider may be a good idea. Dissolving the thread with heat therapy, known as radiofrequency or ultrasound-guided ablation, may be an option for you. This procedure involves using heat to break down the material the thread is made of, making it easier to remove or dissolve. Another option is to have an ultrasound to look for an infection pocket. This may be recommended if there are signs of infection or inflammation, such as redness, swelling, or pain. An ultrasound can help identify any pockets of infection or inflammation and guide the appropriate treatment. It's important to remember that all procedures come with risks and potential complications. It's essential to speak with a qualified dermatologist or plastic surgeon to determine the best course of action for your specific situation. Be sure to ask about any potential risks, the expected outcome, and the recovery process. In conclusion, if you are experiencing a complication with a PDO thread, it's important to seek medical attention as soon as possible. Having the thread pulled out, dissolving it with heat therapy, or having an ultrasound to look for an infection pocket are all viable options. It's important to discuss your options with a qualified provider to determine the best course of action for your specific situation.
