I have a 7-day course of antibiotics to take, plus I'm supposed to soak the toe in hot salted water (preferably epsom salts) three times daily plus keep the area clean & dry. I have some betadine iodine-based antiseptic to dab on it after the soaks.
I visited the open-on-Sundays medical clinic next door to my place & they said to come back in a week if I haven't sought help from my regular GP.
