My Husband Started With Fatigue And Nausea 4-13-15 After Playing

My husband started with fatigue and nausea 4-13-15 after playing golf. diminished appetite (always a hearty eater). nausea relented, but, fatigue is still present. he seemed to be feeling better, but, today seems to have slipped back. just took his temp and by my thermometer it reads 101.4. he is somewhat chilled. He has been anemic in the recent past (6 mos) and has been on iron supplements, but has not had follow up lab work. what to do besides make an apt for follow up lab work?
