Hello, I have been having pain behind and above my right eye for 3 to 4 days now it is quite dull.and constant and sometime becomes a little sharper. It has woken me up in the morning and I am unable to go back to sleep. Cocodamol relieves it but when that wears off it comes back. I am 25 years old, male, smoker, currently travelling Asia, drinking a few times per week, no drugs and no other medication. I believe I need glasses as recently I have noticed I am unable to read things clearly that are more than 10 feet away. I am just worried it is something serious. Can you please advice of any possible causes and what action I should take. Thank you
