I love getting my nails done with a gel or shellac manicure. The polish doesn't chip at all and stays shiny for weeks. I'm just worried about the UV light used to seal the manicure - it is almost like a mini tanning bed for your hands. What are the risks? And are there any bad chemicals in the polish?

For a number of years I have had acne from waist down. I can't find any information on it except for acne of the face and back. I'm embarrassed to wear shorts in the summer. Any suggestions?

1) Over the span of the last couple of years, I have noticed a significant number of moles appearing on my body. They have been appearing everywhere from my neck to my inner thighs. I had one on my neck since childhood, but now have so many more. Is this normal? Is it something I should be concerned with? And does child bearing have any relevance to this happening?

2) I have a mole which has turned very dark purple, and grown a bit in size (still small). This is the second time it has done this — last time was a couple of weeks ago, and it slowly faded back to almost nothing until today. Should I be very concerned about this?

I'm really stressed out because I've been getting recurring urinary tract infections coupled with yeast infections for the last six months. I'm not sexually active and I've been to two urologists and a gynecologist — they've all given me medication but the problems always turn up again. Is one problem causing the other? Can these prolonged problems be doing serious damage to my body? Perhaps you can't answer my questions either, but I'm really at my wit's end. What do I do? I'm tired of doctors and embarrassing exams and I can't understand why this is happening if I'm not having sex. Also, I'm a senior and in five weeks I'm out of health insurance — extending my parent's policy is very expensive and not an option. I'm busy trying to set up interviews, finish a thesis, and do a million things — I don't have time to be running around to more doctors' appointments! What insurance options are there for recent graduates?

I get cold sores around my mouth and nose all the time; I have since I can remember. I know that they can be caused by both physical illness and mental stress. Is there any way to reduce the frequency with which I get them, i.e., diet? Please help me, I feel like a leper.

I am a first-year student and I want to get my nose pierced. This isn't just a whim; I've wanted one for a long time. However, I know that there will come a time when the ring will look juvenile on me. My question: will such a hole close up fairly quickly, without leaving an ugly scar?

As the summer is soon to arrive, I was wondering what type of clothing should I wear to protect myself from the sun? Also, what color works best, light or black? I seem to be getting conflicting answers on the Internet. I am a fair skinned male. Thanks for your help!

I think I may have some kind of urinary tract infection. It came on very suddenly, about three nights ago. And when I pee, there is a burning sensation when my bladder has almost emptied. It's not an STD because I'm in a monogamous relationship, and yes, I'm sure! Please help. Thank you.

I was hoping to wear plugs. You know, the earrings...but do they hurt when you put them in?
