Thank you for your question on ehealthforum.
Any injury to face especially a direct hit on the nose can cause nasal haematoma which collects between nasal cartilage and superficial layer, Very mild and very small blood collections need monitoring, but most of them required surgical drainage as they can get infected and lead to complication like abscess and perforation of the septum.
Please consult your ENT surgeon immediately for the examination, and treatment. Thank You.
