i hit my left thumb in the door while closing it. Initially the pain was unbearable the nail turned blue and black from base to half nail. its the 3rd day still have pain, radiating to left arm, throbbing and swollen at the base, with a slight yellow color. please advise
Hello, it may be entirely a soft tissue injury or undisplaced fracture may also be suspected depending on the severity of trauma.Yellow discolouration may be due to trauma related onycholysis, where the nail separates from the nail bed.Since throbbing pain is felt still on the 3rd day its better to have a physical examination, an x ray if required, along with ibuprofen...which relieves the pain and oedema too..Hope it helps..
