I'm posting this for my grandmother who was in the hospital for a few weeks almost a year ago for serious kidney complications. she was kept on an IV of Dilodin for a very long time and it was positioned right above her right breast beneath her collar bone. after recovery she's noticed that the three middle fingernails on her right hand have not grown since she was in the hospital! and now the skin around her nail beds is cracking and dry while all her other fingernails are fine! this is worrying for myself and her. could it be nerve damage from the strong IV?
