Sorry. 3 or 4 times a year recently I get these tiny blister like spots on my chin, they really burn and gradually get worse with my whole chin swelling up!! I've kept area clean , not picking, clean hands and rest of face is clear. It's always same area and really sore not to mention ugly. It's day one but I know it'll be awful tomorrow. Does anyone know what this is? Seemed silly to go to gp but probably will now as it is reoccuring.
