"No crutches"

My son, student at the University, attended A&E on 20 Nov 2014. Seen quickly due to his pre-existinting conditions following a knee injury. His knee was very swollen, painful and difficult to weight bear. Told he had bleed into the knee bursa. The department appeared almost empty of patients. Following diagnosis he was told to apply ice and take pain relief and left the hospital. He more or less dragged and hopped his way out the A&E, no offer of pain relief or crutches. It was assumed he knew what take pain relief meant or is. The next day his leg has seized up and has no confidence to go back. Following my advice told him to go back to his home town and be seen there.
