Hi, I'm male 40, I've been suffering from from fatigue for about 2 months. I wake up tired, I yawn and my eyelids feel heavy. I also have a mild fever that goes on and off. I can feel good one day and think i'm recovering, then the next day I have this slught fever. I have tinglings/burn feeling in the feet that I feel more during the night. Sometimes the tingling is very light or goes away for a while, sometimes it's burning.
The doctor made me take blood tests, everything came normal except for Vitamin D which was excedeeingly low 7,9ng/mL. He prescribed me Vit D supplments, after 4 days I don't see much difference.
The vitamin D deficiency might explain the fatigue, but why do I have on and off fever and tingling in feet? And what caused the deficiency? I didn't change my diet and my habits. I know there was much less sunlight during the past months due to winter and that is normal to lose vitamin D in that period but I suspect there is an underlining cause.
