Hello Thanks for posting this question in HCM I am a neurologist responding to you Let me tell you that any medical symptom can be related to various causes and this applies to headache. Headache can be due to various causes and it can be due to brain tumor, infection, head injury, migraine, cluster headache, low or high pressure in the brain and so on. Further presence or absence of accompanying symptoms with headache can help us narrow down the possibility. It is important to know about the presence of vomiting, loss of consciousness, bleeding from nose ear, weakness of legs, hands etc. I have noted your problem and you will benefit with the following approach 1. In the absence of other complaints, as discussed above, you can observe yourself and take simple analgesics like paracetamol. If the headache persists for more than 2-3 days visit a local neurologist 2. You may opt for immediate neurological evaluation and CT scan of brain to make sure that there is nothing wrong and follow the advice of local neurologist Hope this will help you
