Thank you for your question. Your nose is moving towards a more healthy place where it will be more resistant to any minor bumps. Please continue to monitor your face and nose. I suggest that you follow the advice of your board certified facial plastic surgeon and keep them appraised of your healing as you continue to monitor this bump/swelling.
