Restless legs syndrome (RLS) causes a powerful urge to move your legs. Your legs become uncomfortable when you are lying down or sitting. Some people describe it as a creeping, crawling, tingling, or burning sensation. Moving makes your legs feel better, but not for long. RLS can make it hard to fall asleep and stay asleep.
In most cases, there is no known cause for RLS. In other cases, RLS is caused by a disease or condition, such as anemia or pregnancy. Some medicines can also cause temporary RLS. Caffeine, tobacco, and alcohol may make symptoms worse.
Lifestyle changes, such as regular sleep habits, relaxation techniques, and moderate exercise during the day can help. If those don't work, medicines may reduce the symptoms of RLS.
Most people with RLS also have a condition called periodic limb movement disorder (PLMD). PLMD is a condition in which a person's legs twitch or jerk uncontrollably, usually during sleep. PLMD and RLS can also affect the arms.

Seizures are symptoms of a brain problem. They happen because of sudden, abnormal electrical activity in the brain. When people think of seizures, they often think of convulsions in which a person's body shakes rapidly and uncontrollably. Not all seizures cause convulsions. There are many types of seizures and some have mild symptoms. Seizures fall into two main groups. Focal seizures, also called partial seizures, happen in just one part of the brain. Generalized seizures are a result of abnormal activity on both sides of the brain.
Most seizures last from 30 seconds to 2 minutes and do not cause lasting harm. However, it is a medical emergency if seizures last longer than 5 minutes or if a person has many seizures and does not wake up between them. Seizures can have many causes, including medicines, high fevers, head injuries and certain diseases. People who have recurring seizures due to a brain disorder have epilepsy.

The tailbone is the small bone at the bottom of your backbone, or spine. Tailbone disorders include tailbone injuries, pain, infections, cysts and tumors. You rarely break your tailbone. Instead, most injuries cause bruises or pulled ligaments. A backward fall onto a hard surface, such as slipping on ice, is the most common cause of such injuries. Symptoms of various tailbone disorders include pain in the tailbone area, pain upon sitting, pain or numbness in the arms or legs due to pressure on nerves in the tailbone area, and a mass or growth you can see or feel.
You may only think of tears as those salty drops that fall from your eyes when you cry. Actually, your tears clean your eyes every time you blink. Tears also keep your eyes moist, which is important for your vision.
Tear glands produce tears, and tear ducts carry the tears from the glands to the surface of your eye. Problems with the tear system can include too many tears, too few tears, or problems with the tear ducts. Treatment of the problem depends on the cause.

Kids often begin drinking to look "cool" or fit in with their peers. Parents can help their kids avoid alcohol problems. Open communication and conversations about drinking are important. So is being involved in your child's life. Get help for your child if you suspect a drinking problem.
