### Human:\nchest neck arm pain began 2or3 years ago aft heavy work. lasting 30 mins. now any activity even showerlasts 8hrsor more\n\n### Assistant: well i recommend you get this checked out. heart problems can hit like lightning (heart attack) or come on gradually. it sounds like you may have a heart problem that's becoming gradually worse. of course this can only be determined with a physical examination and some other testing performed by your health care provider. chest pain that lasts 8 hours is nothing to ignore. please get medical attention as soon as you can. all the best to you!
