Hi welcome to the health care magic Cause for headache should be searched rather than trying only heat application.... If after waking up headache persist for considerable duration then cause can be searched for that High blood pressure, hypoglycemia, stress, smoking are some causes for headache... Teeth infection, ear infection, viral flu also can lead headache... For headache relief when needed paracetamol can be prescribed... Anxiety, depression, constant work on computer etc are also cause of headache... So try to find out cause for headache like all above mentioned causes Take care Hope this will help you You can ask further if having query
