Headaches when fatigued/overworked
My condition diagnosed by a doctor is kidney yang deficiency and liver blood deficiency.
As I get better and increase my daily activity, I notice that if I accidentally go overboard, I get a headache/dizziness for maybe a day. After resting fully in bed and eating it subsides, sometimes I have to bed rest an entire day.
Was wondering what is the reason for this. From my understanding yang is needed to create blood and blood deficiency can cause headaches and dizziness. If I exhaust my yang in the day it also affects my blood and thus I get fatigue + headaches? And blood deficiency also affects my sleep -> extra vivid dreams and waking up in the middle of the night?
Was wondering if that was correct, if not what’s the reason for it?
Thanks.
