A long time ago I would randomly get extremely cold extremeties which would go numb and turn white (usually my toes). It wasn't a big deal as it went away in a few minutes. This stopped for years (i'd say this happened when I was 13), including years in which I played football and lifted weights.



Now i'm 19, a college student, and the problem has returned. Only my toes do it, and it only happens when i'm at my dojo doing jujitsu. It seems frequently to be after a fall (a "kip" for those familiar) but its happened randomly at other times too.



Along with that:

- fatigue. I could sleep for a good 10 hours and still take a nap during the day. I hate this - I feel like i'm wasting valuable time.



- shortness of breath working out. I'm not in the best of shape (5'8 175) but i'm not "fat" either. There is no reason I should be getting out of breath faster than some of the more clearly out of shape people. Especially since I played football from age 7 til age 14, and then again from ages 17 to age 18 (and played defensive back and running back). I've slacked off lately with getting in shape, but something doesn't seem right here. I did notice the shortness of breath and tiring easily during my latest football stint.



- dizziness when tired. I don't mind the shortness of breath so much, but what gets me is that when I get tired and out of breath, I get dizzy and can't bear to stand.



- low quantity of urine. Now, i'm not sure exactly how low, but I know that my pee is usually less powerful and lasts shorter than what I hear in the bathrooms. Unless I hold it in all day until I feel like i'm going to burst. Usual bathroom trips produce urine, but not as much as what I hear as being "normal."


i was thinking anemia, but with the problems going back so far, i'm not sure what disease could cause it that wouldn't have shown up elsewhere in health problems.



I was also thinking "iron deficiency" as the latest outbreaks of problems have happened when I moved in with my mom (not a fan of cooking; ordered out a lot) and now again while i'm at college and have to live on dorm food.



In a list of symptoms of "iron deficiency," I qualify under all except one.



You could be iron deficient if you.....




..... Are unusually tired;


..... Have reduced ability to exercise comfortably;


..... Have poor stamina;


..... Get frequent infections; or, <------doesn't apply to me


..... If you are lethargic.

I've also had a sore tongue before, frequently associated with iron deficiency anemia. And I am a chronic nailbiter (could that qualify as pica?)

any thoughts? Should I try taking iron supplements to see if that helps? Or should I see a doctor right away?
