It is very difficult to pinpoint the cause of your headache based on the limited information you have provided.
However, the common causes of early morning head pain are Sinusitis, Inadequate/ Improper sleep (Sleep Apnea), Cervical pain or Spectacle power.
Kindly consult a Physician and an eye specialist to evaluate for these conditions.
Let me know in case you have any queries.
