A fever and headache that is very severe can be dealt with in the following way: First of all, you must stop all the work at hand for rest and drink more water appropriately to promote the elimination of toxins from the body. You can consider cooling the temperature unreasonably by applying hot towels to the forehead or using ice cubes to the armpits and femoral artery pulsations. Secondly, it is also important to take medications such as aspirin, ibuprofen tablets or fen-phen to reduce fever. Consider Chinese medicine treatments, such as treatment with acupuncture or massage of the head, for the purpose of relieving the headache. If the fever and headache are particularly severe, please go to the hospital for appropriate tests, such as routine blood tests to see if there is an increase or decrease in white blood cells, and neurological tests can be done.
