<s>[INST] Hello doctor, I have been having constant moderate to severe headaches for the past four years, and I mean every single day, all day long, from the time I wake up to the time I fall asleep. Nothing OTC medicine has helped, nothing prescribed has helped. I have been told it is just a tension headache. I was prescribed a medicine but cant remember the name, it did not work. I had a CT scan done was told it came back clear. No one has been able to tell me why I have these headaches? It is getting me to where it is hard to function. I just cant take it anymore. I am waiting to see a specialist but not sure yet when that will be. The headache is not just on one spot, it is on my whole head, top of my head, the sides, my forehead, the back of my head, my neck, my eyes feel constantly strained, and my ears are always ringing. A doctor told me that my ears could be ringing if I take medicine on a daily basis. So far doctors could not figure out what it could be. Please help. [/INST] Hello. I would like to know some details about your headache. What is your age? Since when you started to have headaches? Is it four years only or even before that? Where do you feel that headache, in which areas of head? What kind of headache do you feel heavy, throbbing, stretching, bursting, shooting pain, electric current like pain, or some other kind? Is it severe, moderate or mild? Is your headache episodic or persistent? In episodic headache, how long time one episode of it lasts (from onset to complete relief without medication)? How frequent are these headache episodes before and now? Like how many times in a week? As you mentioned is it two times a week since beginning? Do you feel any vomiting or watering from eyes or redness in eyes or nasal congestion during headache? How is your day to day mood? How is your sleep and vision? Have you noticed any trigger factors for this headache? Do you have any ear discharge or hearing impairment? What medicines haveyou taken before and in what dosages? Are you taking any medicine now also? </s>
