when does blindness happen after the injection of fillers ? hours? days? the dr injected me with hyaluronic acid on the sides of my nose (from middle to upper part near eye) , she said i need a bigger nose for my face !! i got a bruise there and swelling , it's been one day since injections , are there any risks of blindness ? also the fillers on the sides of the nose are giving me headache ,,lots of pressures, should i remove them?
