I've dropped a mug of boiling water on my foot and I'm beside myself with pain. The top layer of skin has wrinkled over an area of about 3x5 inches, looks obviously burnt and is slightly swollen. I've had it in cold water for over an hour, now it's dry and under cling film. The NHS website says go to A&E but I really don't want to go on a Friday night. I'm getting a bit agitated with the pain (have taken some paracetamol). Any suggestions?
