was going down my stairs,slipped and my toes where bent under as i landed on foot on next step,then i came to a stop in my knee. I had intensse pain straight away along with light bruising and swelling. This morning it if still swollen and bruised more. I can walk on it, but it has pains in it. I do not know if its a sprain or break. The big toe is the worst in color and pain, but the toe next to it is swollen right above the first two joints on it. should I just treat it at home or go to the GP?
