I have been struggling with fatigue for about a year. I have seen my GP repeatedly along with an endocrinologist. All of my tests are perfectly normal. I'm tired enough that it is affecting my job and everyday responsibilities.
I'm a healthy 31 y/o woman other than this fatigue. I have zero other symptoms that I can think of. I eat well, I'm not stressed out or depressed, and I get 8 hours of sleep a night. I do take Vitamin D, but that has been for a number of years and my current numbers are excellent. I wake up semi-refreshed and then just get more and more tired as the day goes on. Exercise doesn't make me more tired. It might even help a little, but not enough. I have had a ton of blood work done and everything was normal. It included glucose & A1C, CBC, metabolic panel, various hormone tests, and thyroid (TSH and T4 Free). I also had a negative test for sleep apnea.
My doctor prescribed me an ADHD medication when my fatigue got so bad I couldn't even think straight, and it helped immensely for the first couple weeks. After that, it didn't help anymore than a cup (maybe two) of coffee. My GP had me increase the meds and after trying it for a couple weeks, all that did was make me jittery and tired at the same time.
My next step is to follow an elimination diet for food allergies. I have a couple allergies and am aware that they can present in odd ways, so I figure it's harmless to take a look from that angle.
Can anyone here give me other ideas or questions I can ask my doctor? My GP isn't bad, but I'm pretty sure he has run out of ideas and I'm going to start getting brushed off.
