I took a tumble last week and the grazes feel really slow to heal. Day 5 and the one on my knee is still raw and in a couple of places has bled today. I’ve tried Savlon, anti septic cream and a spray on plaster but nothing is helping. I’ve cleaned it tonight (which turned my stomach!) and I’ve now put La Roche Posay cicaplast b5 baulme on it. But nothing is helping!
