I broke my nose and have a few rugby matches in the following weeks. Is it okay if I play?

Yes you can play. Athletes break their noses all the time and play. If you wish seek the advice of a doctor. In my life I broke my nose 7 times and just kept playing. I have never regretted it. If you had a concussion it is a different story and you must see a doctor for your safety. My Best, Dr C

You did not mention if you had surgery following breaking your nose. If you did, I would not play rugby until your surgeon gives you clearance. An exam is needed to answer this question. Consult with a Board Certified Plastic Surgeon for an exam, and to discuss your activities.
