My boyfriend is an active, healthy 53 yr old man who keeps coming down with body aches and muscle fatigue. He has lost weight, looks pale and it worries me. He's under a normal amount of stress for a man that owns and operates his own business, but his fatigue is getting worse. His appetite is fair and his sexual function is excellent. He has a physical coming up in a couple of weeks, but am wondering if there are any specific questions he should ask his doctor concerning his symptoms? Thanks!
