I ve been extremely fatigued, had problems concentrating, and had a headache for 4 months now. Had EEG and MRI. Neurologist said vitamin d, b12, iron, and folic acid deficiency. Taken supplements for 2 months. Still don t feel any better. Have hyperthyroidism. Endocrinologist has checked levels 3 times in the last four months. Headache has gotten a little better, but recently started having problems with armpit odor and acne.
