Hi i have high fever around 103 to 104 every day since 1 month and my doctor asked me to take amoxixillin 500mg 2wice a day. but im still not cured?

FUO?: There are too many causes to even guess, especially since you don't say what other symptoms you have. Fever of unknown origin (FUO) to 103-104 could be very serious, and whatever the cause, it clearly is not responding to amoxicillin. Don't stop taking it unless your doctor advises it -- but for sure return ASAP for further evaluation. Or ask for referral to an infectious diseases specialist.
