got a 2nd/3rd degree burn from my oven a week ago. I waited a few days to get it looked at but have since been an urgent treatment centre twice to have it dressed with hydrocolloid patches. I woke up today with a headache and feel a bit nauseous, with are on the symptoms to look of for list on the burns leaflet. Should I go back to have it looked at before my next appointment in 3 days time, or just wait?
