The commonest causes I can think about are as follows: Sinus pain being referred to the temporal area is known to occur. Vascular problems like superficial temporal arteritis can also cause this. Hypertension can cause such headache. Lack of sleep and rest. Hypertension is a known cause of headache. Viral infection of body can cause similar pains.

Once the diagnosis is made it will be easy for management as per the cause found. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. T. Chandrakant, General Surgeon
