The captain and I smelled oil fumes (gym sock smell) climbing out. We went on oxygen. Around 18;000 feet the smell dissipated so we took the masks off. The smell came back on the descent so we went back on oxygen again.I was scheduled to split off the trip in ZZZ so I went home. I developed a bad headache within a couple hours; had very red eyes; and had severe fatigue over the next few days. It's now 31 days later and although the bad headache abated; I've had a dull headache every day since this happened. Excedrin and Advil don't help. I've never had a headache last this long although I have had headaches after fume events in the past.[Suggest] proper maintenance of engine or APU bleed air source.
