Will injury to nose cause droopy nose tip? I still have swelling after 4 weeks

Thanks for the question. I recommend you to have a personal consult for better advices or send your photos to give you recommendationsKind regards 

Thank you for your question.  Unfortunately, swelling to the nose takes more than just a few weeks to resolve. Please be patient and allow the swelling to resolve and see if permanent damage due to trauma has been made. Consult a Board Certified plastic surgeon to evaluate you and offer possible options to correct if that's what is needed. Best wishes, 

without seeing any pictures or knowing the degree of your injury, it's hard to say. That being said, it's unlikely that it will cause a droopy tip as a great majority of nasal injuries do not cause one. However, injury to the supratip area and continued swelling can lead to the appearance of a fallen tip. My advice to you would be to be examined as that will give you the most accurate answer. Sorry to hear about your injury - best of luck!
