Thanks for writing in.
It would have been better if you had mentioned your age and nature of work.
Any family history of Migraine? (Migraine can present with headache and nausea)
Watching Computer Screen/Laptop for long duration.... ? Could be Computer Vision Syndrome
Other possibilities are Vertigo, Anxiety, Motion Sickness
, Stress and Lack of adequate sleep.
I would advise you to get a couple of investigations done like TSH, Hemoglobin
, Blood sugars etc to rule out thyroid disorders, anaemia , diabetes
Please do visit a doctor for a thorough evaluation.
Hope this helps.
