I've come down with chickenpox. Should I stay home from classes even though 90 percent of adults have already had it and are thus immune? If I take great care washing my hands and avoiding coughing anywhere but into the crook of my arm, will I be reasonably assured of not spreading it?

Is there any cure for itching when I wear wool clothes? In the winter time, I love to wear my wool pants and sweaters, but they make me itch. I've tried wearing pantyhose underneath, but it doesn't work.

Help.

I have two piercings in each earlobe; however I have not worn earrings in the second set of holes for several years. Recently I tried to insert earrings into the seldom-used pierce holes. One earring went in with no problem, but the second did not go through after several attempts (I actually gave up because my last attempt bent the earring post). I have tried inserting other earrings but they also will not go all the way through. Is this something I can fix myself? Do I have to get the same hole professionally re-pierced? Will there be problems with scar tissue at the site?

I am African-American, but my skin is not that dark. I was never told that I needed sunscreen and when I worked in a daycare I was told in a very delicate manner that only the paler children needed sunscreen. I've been out in the sun for extended periods of time and was wondering if sunscreen is necessary for someone of my complexion. If so, what strength?

I was recently diagnosed with impetigo & was wondering if I had oral sex with my boyfriend if he'd get genital herpes. Thanks!

I was in the sun for seven hours yesterday and I got a pretty bad sunburn. My face has blisters all over it. The redness is severe, and the pain is severe. Any suggestions that you may have will help. To top it off, I am a diabetic and am worried about infection of the blisters.

I find choosing among all of the available sunscreens and sunblocks to be very confusing. Of the following three products I am currently using, which one is giving my skin the most protection: sunscreen SPF 30 with UVA, UVB, and IR sun protection; sunblock SPF 17 with UVA, UVB, and IR sun protection; or, sunblock SPF 50 with UVA and UVB sun protection? By the way, what is the difference between a sunSCREEN and a sunBLOCK?

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?
