But you said it may be infected. You should try putting some neosporin on it and leaving it alone to see if the irritation goes away. Also some people will have prominent veins on their forehead which pulsate with anger and an increase in heart rate (Clint Eastwood for example).
The best thing to do would be to try not to worry about it and give it some time to heal.
