Abnormally high levels of sex hormones cause brain and adrenal glands to perform excessive dopamine-norepinephrine-epinephrine conversion. In other words: there is a big change of body chemistry when man or woman practices over-masturbation.
Pineappleitis: Pineapple commonly causes minor skin irritation because it's highly acidic. It's common for your tongue to feel gritty, itchy and mildly painful after eating pineapple. If you develop severe pain, itching, burning or swelling in your tongue from eating pineapple, you should talk with your doctor.
One cause of a burning tongue could be a condition called Glottis, which does not affect the lips or any other part of the mouth other than the tongue. The condition results in an inflamed, painful and swollen tongue and can involve a burning sensation. With Glottis your tongue may also be smooth and tender, and you may experience problems with chewing and swallowing. The color of your tongue with this condition will generally be dark or bright red or pale. The painful burning and swelling of Glottis can have many causes in itself, among them being such conditions as stress, anxiety and depression, leukemia, hormonal changes, as well as specific tongue cancer.
