Dear Dr. Cory:
I have allergies(过敏反应). It feels like something is in my throat. What is it and what should I do to
help it?
Christa
Dear Christa:
You might be feeling mucous in your throat.The membranes there make mucus to keep nasal
passages(鼻腔)moist and clean and to warm the air that we breathe.But sometimes our bodies make
too much mucus, and it can collect at the back of the throat. Drinking lots of liquids, especially warm
ones, may help.
Dear Dr. Cory:
Sometimes when I don’t wear any socks with my shoes I get blisters(水疱). What are blisters? How
can I avoid them?
Jacy
Dear Jacy:
Blisters occur when something(like the back of your shoe)rubs against your skin and causes tiny
blood vessels to leak fluid(液体). The blister acts like a pillow to protect damaged skin while it repairs
itself.
The best way to prevent blisters is to avoid“rubbing”spots.If the problem is your shoes, wear socks
and shoes that fit to help prevent blisters.
Dear Dr. Cory:
I like reading your column. It tells me a lot about the body and how it works. I have a question for
you: I have not been airing my feet out lately and the bottoms of them have been turning crisp(起皱的)
and the skin is peeling. Why?
Aaron
Dear Aaron:
People whose feet get wet or sweaty while wearing shoes may develop athlete's foot, caused by a
fungus that likes warm, damp skin. The fungus is easily passed from one person to another, so public
places such as locker rooms or showers are real hot spots. It's most common during summer in people
who rarely remove their shoes, and in people who sweat a lot. It can cause bumps, redness, itching,
and peeling of the skin, often between the toes.
Anti-fungus cream, now available without a prescription(处方), cures the infection. Your doctor or
health care provider can help find the cause of the problem.
