just protect it from re-injury. the nail bed may be more sensitive. keep in mind that there may be a brand new nail already present underneath the damaged black one. if you did not injury the nail matrix (the cells that grow a new nail) you may have a pleasant surprise of finding a fresh nail covering the nail bed after four months.
