Then, let's look at the article about the most popular medicine in the world as well as in Korea and their side-effects written in Jan. 23rd, 1996, Chosun Daily.
The title of the articles is "Tylenol, forbidden for weak liver"
"Recently, a family of victim who deceased from liver failure after taken Tylenols sued the company in the U.S. and has been in denunciation for its side-effects. This incident indicated the coming of criticism in Korea as Tylenol is one of the best selling painkillers in Korea. Tylenol is one of the acetaminophen medicines and has been widely known to be safer than Aspirin that it became popular as the pain medicine for young ages. There are about 100 kinds of acetaminophen medicines sold in Korea including geborin, penzal, saridon-A, etc.
Professor Byung-Moo Lee (Sungkyunkwan University, Pharmacy, Toxicology class) asserted that "person with weak liver or with liver-related disease should give extra care with taking Tylenols. As a number of Korean people, especially, suffer from liver disease, the government should have an immediate solution such as by revaluating its effects and side effects."
This is not the first notice about Tylenol being harmful to a liver.
In 1966, the English Medicals, for the first in the world, has reported that overdosing Tylenol can cause acute liver failure. For an adult, in Korea, taking two 0.5g Tylenol pills 5~6 times a day can be lethal when only taking 2 pills is safe. The marketing manager of Yuhan Corporation, one of the Tylenol sale companies in Korea, said that, "taking many pill at a time can definitely cause side effects however, when taken for what it says to take, there won't be any big problems." But, Medicine expertise in Korea asserts that "If this drug is taken constantly, even with regular doses, it can cause critical damage to a liver.
Minor Liver Toxicity shows minor symptoms such as anorexia, vomiting, perspiration, etc, but when it gets serious, it can cause jaundice, kidney failure, myocardium disorder, lethargy, liver necrosis and even death.
Professor Lee pointed out that "ones with weak liver or person who chronically takes Tylenols can possibly haves acute hepatitis or liver fibrosis even from taking 6g of Tylenol a day.
This article consequently seems to have had firm objective evaluation about the side effects of painkillers. One of the medical archive said that headache, born with the human race, has been one of the unsolved mysteries. Then, why do we have headaches? The cause of headache can come from all complex ways of blood vessels, muscles, mentality, or eating habitats etc.
In an experiment of Dr. Markovich, most of patients suffer headaches relating to head and neck diseases and the main cause was the skeletal discord. He categorized the causes of headache as 10% caused from blood vessel and infectious diseases, and 90% from muscular contractions and convulsions. He also reported that the first main cause of headache was from the muscular contraction around the neck, especially abnormal contractions and pain of the trapezius muscles. As trapezius muscle contracts, it pressures the 2nd cervical nerves (large occipital nerves and small occipital nerves) which goes over the occipital region. These nerves goes over occipital region and spread over occipital scalp, temporal area, auricles, angulo mandibular, and read area of the eyes that any of these areas can cause pains.
Recently, Professor Dong-Yeup Shin from Medical school of In-Je University said in his recent dissertation that most patients with aka tension-type headaches were actually the patients suffering from myotonic headaches. This myotonic headache was found mostly in women in their 30~50's. Peculiar things to know are that patients complained of the pains around their neck and head. The symptoms were as follows: head feels heavy, having dull headache, feel tightness on head, feel shaken, feel pulling behind the head, feel dizzy, feel like eyes popping out, feel vomiting. Professor Shin also said that the pain arouses from pressed bloodstreams and nerves from muscle fibro contraction of tensioned muscle from many causes such as stress, muscle fatigue, overdrinking, smoking, or cold.
It would be easy to take care of headache if we know their actual causes. But when we don't know its causes, we would have to deal with the headache itself. Then, let's look at the causes of the headache that are related to teeth only.
