I have been sick with over 102 degree fever for four days straight now?

I have been sick with over 102 degree fever for four days straight now. I have been staying hydrated and rested and eating well. this fever ust wont break. I have tried ibuprofen, tylenol, and naproxen (within recomended time and all. not all together.) but with no affect on the fever. should i be worried?
