Hello, i am a 21 year old male. I have had a headache now that is currently lasting 4 days, im starting to get a bit worried. Sometimes the headaches are mild and sometimes they really hurt, a sort of burning sensation, it seems like the pain is all over to. When i move it hurts and even when im still, it also keeps waking me up. I have also been having a weird sense in smell and my taste to, i feel like i have a dry throat all the time however much i drink. And things seem to smell a bit different. Ive been feeling really hot to, not sweaty just been feeling really hot. I have not been a person who suffers with headaches and not a person who ever drinks alot of water. Being a young male i have been out alot recently, actually every night since last monday (sunday today) with friends socialising and drinking, casual drinking most nights with a few late ones. I go to the gym, eat well and drink water most of the time and have never had problems before. Any suggestions? Thank you.
