Two months since balloon sinuplasty and now bleeding when I blow my nose?

Thanks for your question. While it is impossible to know what is going on with you without an exam, it sounds as if you are having a typical response to just balloon sinuplasty. In many situations the results may only be temporary due to the nature of the technique using balloons. The bleeding may be a result of the dryness of the air in winter, especially indoors. Please consult with your local sinus surgeon for specific details. Hope this helps.
