He has also vomited twice in last 2 weeks but kept playing afterwards. He has also had terrible nose congestion for around 6 months that is just not going away.

I recommend trying one of the steroid nasal sprays, these are very safe and has very minimal systemic absorption you dont need to worry about .you can use : eliminate nasal spray twice daily, it shows a great response with my patients I hope this helps
