Q. My grandmother told me she has BPPV and that it makes her head spin. What exactly is this BPPV?
Benign Paroxysmal Positional Vertigo (BPPV) usually strikes when you change the position of your head.
Vertigo is the feeling that either you or your surroundings are spinning. It is more than being just lightheaded or dizzy, because you are subjected to the illusion of movement. If you feel your body is moving, you have subjective vertigo. When you sense that your surroundings are moving, you have objective vertigo.
Q. I have a friend who is undergoing radiation treatments for cancer. I was wondering how this works. Doesn’t the radiation burn everything it touches?
Radiation therapy kills cancer cells by damaging their genetic material. This process prevents the cells from growing. Radiation attacks all cells in a targeted area, but most healthy cells recover when treatment ends.
Q. Are there different kinds of angina?
Yes. There is stable angina, unstable angina and variant angina.
Angina, or angina pectoris, is the medical term for chest pain or discomfort usually caused by coronary artery disease.
Angina (pronounced an-JI-nuh or AN-juh-nuh) hits when the heart doesn’t get enough blood. This usually happens when there is a narrowing or blockage in one or more of the vessels that supply blood to the heart.
Angina can come from exertion. It may make you sweat or lose your breath. The pain can strike your arm or neck, too.
Q. I am petrified of spiders. Is my fear justified? Are they dangerous or just creepy?
Spiders are not aggressive. They bite you only in self-defense. Most bites by spiders are harmless. However, there are dangerous spiders. Spider bites are responsible for fewer than three deaths a year in the United States.
Spider bites have caused people to have limbs amputated. These victims refused to get medical remedies early and suffered from large wounds that became infected.
Q. I was racing down the cellar stairs a few days ago when I slipped and fell on my tailbone. I’ve had pain ever since. What should I do about it?
The coccyx (tailbone) is made up of three to five vertebrae at the lower end of the spine. Most people have a coccyx of four of these spinal bones. The coccyx functions as an attachment site for muscles, tendons and ligaments.
Coccyx comes from the Greek word for cuckoo. The coccyx’s shape is like the beak of a cuckoo. The human coccyx is considered a vestige of what was once a tail.
Q. What are the options for treating prostate cancer?

Q. I get the winter blues every year. I was wondering how many people suffer the way I do.
The medical term for winter depression is Seasonal Affective Disorder (SAD). Symptoms usually begin in late fall or early winter and go away by summer. A less common type of depression occurs in the summer. SAD has been linked to a biochemical imbalance in the brain prompted by shorter daylight hours and a lack of sunlight in winter.
