Thanks for your question on Healthcare Magic.
I can understand your concern.
In my opinion, we should first rule out anemia (low
hemoglobin level) in your case because of your pale complexion, easy fatiguabilty and headache.
So get done
Complete blood count and if hemoglobin level is low then you will need
iron supplements.
Other likely cause for your symptoms is
migraine.
So avoid stress and tension, be relax and calm.
Drink plenty of fluids orally and keep your self hydrated.
Avoid excessive sun exposure. Avoid fasting and take your meals timely.
Take sound sleep of 6-8 hours. Take
paracetamol for headache.. Don't worry, you will be alright.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
