Advice PLEASE: 3 year old, fever of 103 on and off for 8 days, runny clear congested nose, cough, congestion ?

Sorry, I did not have to read all what you typed. All I had to see was 103 and 3 y/o. I do not care what your kid tells you. You are the parent and 3 years old and 103 degree temperature is not good. Your kid might go into seizures if you let this go on.
