NAVY pains(literally)?

i just started working in the navy, i also lift weights and stuff on the side. recently ive been experiencing alot of pain in my upper forearm and lower bicept in both arms. is this normal, am i just getting used to the job? or is it a more seriouse problem like golfers elbow. i cant really stop and rest but stretching and ice dont really seem to do much, its only been happening for a few days now though. i just hope its nothing serious
