Hi, thanks for asking from HCM. I can understand your concern. Such type of headache occurring before and after sleep is : Tension headache - this is a dull type of headache, whole head, band like sensation around forehead, increases with stress/prolonged computer work/sleep deprivation. It is less responsive to medication. You can match your symptoms and suspect it. Other than this, headache due to mass lesion may cause pain in lying position due to rise in intracranial pressure. It is mostly in early morning, occurs with vomiting, relief after vomiting. To differentiate between headache, it needs evaluation : consult doctor for examination : baseline CT head or MRI brain is needed as headache is of 3 week duration : get vision examination, BP check up, air sinus examination to rule out any contributing factors. After confirmation, stress or tension headache can be treated by : rest : proper sleep of 8 hours daily : avoid mental stress : take tablet Diclofenac sodium after proper prescription : head massage : still no relief, consult doctor or ask another question Hope it will help you. Thanks. Take care.
