You've got the look. (GL Body: Q&A).

I'm 12, and I've been wearing glasses for two years. I think I look nerdy. Am I too young to wear contacts?

There's no perfect age for getting contacts. Optometrist Dr. Jeanine Ianole says, "It depends on your comfort level with the responsibility, and whether or not your parents and eye doctor agree." An Indiana University School of Optometry study finds kids 11 to 13 usually can handle contacts with no trouble. While eyeglasses are treschic, contacts can be a great alternative--they won't fall down your nose during cheerleading. If you despise your "four-eyes," contacts can do wonders for self-confidence, too. Heck, you might get the nerve to ask your crush to the V-day dance. Remember--eye contact!

After three heavy days of my period, it goes away. I think it's over, but then it comes back for two more days. Why is this?

Don't sweat it. Gynecologist Dr. Duncan Turner says irregular periods are normal during the first year or so after you first get your period. It's also not uncommon to have a heavier flow toward the beginning of your cycle. But your period shouldn't go longer than seven days. Keep a calendar to record your periods, including how heavy or light the flow. Bring the calendar with you to your next doctor's appointment, and talk to her about your irregular flow.

My feet are itchy and red, especially my toes. They are cracked and gross. What is it?

Sounds like you have a nasty case of "creeping crud," otherwise known as athlete's foot. Dermatologist Dr. David Herschthal says, "It's a fungal infection that itches between the toes, and there's usually a white buildup of dead skin." Pick up an over-the-counter cream, like Lotrimin or Tinactin. If it's not better after two weeks, see a dermo pronto. It could creep into toenails (and that means no pedicures, girls). To avoid future outbreaks, dry feet well after bathing (don't forget between your digits), sprinkle on some preventive powder (try Tinactin Super Absorbent Powder) and always wear socks with your sneaks.

I play soccer, and my calves and ankles are sore. The pain goes away when I play but, at night, I can barely walk. What's wrong?

Ouch! According to the Journal of the American Academy of Orthopaedic Surgeons, over 2.2 million kids develop bone and muscle injuries from sports. Because your bones and muscles are still growing, it's easy to get injured if you don't train properly. "Kids have to be in tip-top shape and have flexibility in the hips, ankles and knees to avoid wear-and-tear and muscle strain in legs," says orthopedic surgeon Dr. John Sarwark. He recommends seeing a physical therapist for strengthening and stretching exercises. Also, cover the sore area with an ice wrap. Still in pain? See your doc!
