How do i make the thermometer register higher while under my toung?

Firstly you should be questioning why you have bad headaches. When are they happening? Are they happening at the same time of the day? Are they every day? You might need glasses or contacts to help you see better, that can give you a headache. If you drink lots and lots of soda or eat lots of sugar you could be crashing later in the day which could give you a headache. You could have a sinus infection, etc. In short, do something about it, don't just try to get out of it. You're obviously in need of some schooling with bad grammar and punctuation! Tongue...

You shouldn't be faking sickness but if you must.. rub it around your fingers before you stick it under your tongue. like you are giving an indian burn or a friction burn.or the rubbing you would do to say money with your hand... but not too much or it will go too high with the heat..and easier thing is pickle juice and salt. It will cause you to vomit.. or tell them that you have diarrhea ... no one ever checks that. Have you tried being honest and telling them that you have headaches... ? When I was in school I used to develop sharp pains behind my eyes so bad I wanted to scream but couldn't because I was terrified of the pain it would cause. We later discovered that I was allergic to the person's next to me perfume. It was the only symptom that it gave me and we would have never figured it out if I hadn't told someone when I was having them and when they went away.

on planet of the apes the apes hid super heated rocks in a bed and the girl in the bed had a high temp. hmmm. i suppose hot rocks arent really very available at school though. other than that run the thermometer under hot water.

stick it in your butt
