"Access to services"

My 17 year old son attended the minor injuries unit/walk in centre at Accrington at approximately 6.30pm yesterday and was told there was too many patients for him to be seen. He had suffered an allergic reaction to his eyes and both eyes were swollen and closed making it very difficult to see. The person on the desk may have thought his eyes were swollen because he had been fighting or not taken him seriously because of his age, either way I don't feel it is appropriate that someone made this judgment and sent him away without any advice on where he could obtain treatment. If the allergic reaction had affected his mouth or airway there may have been a more serious outcome. He did receive treatment at Blackburn later yesterday evening and the swelling is now reducing. I have previously attended this hospital and always found the staff helpful and therefore I am surprised that he was turned away in this way
