I am a young, white, tan, female and I have noticed that my stomach has become discolored. It is almost spotted-looking. Is this the side effect from birth control pills, or does it sound like a more serious problem?

Sadly, today I found out that a friend of my family has just passed away. The cause of her sudden death was a brain aneurysm. I have been researching brain aneurysms and have found out that oral contraceptives are thought to sometimes cause them. I am 19 and I am taking birth control, and now I am very worried. Can you give me some statistics about brain aneurysms linked to oral contraceptives? Thank you.

I have heard numerous reports in the media where they make mention of the "live flu virus" in the flu vaccine, specifically "flu-mist." This is mentioned in conjunction with a warning to avoid contact with this and that (yadda, yadda) for a certain time period. This confuses me. I was under the impression that the flu vaccines contain dead viruses and that it was not possible to catch the flu from the vaccine. Which is it?

My partner is always getting colds, sinus infections, and other nasties during cold and flu season. I've seen him through strep throat, stomach flu, and 16 months of sinus infection flare-ups. It's important to me to take care of him when he's ill, and I know he appreciates the help, but during the school year I get nervous about the risk to my own health and the potential for missing classes/work. What are some ways (short of wearing a mask...) to keep myself from catching all of his bugs without leaving him sick, sad, and lonely?

I'm wondering about Lyme disease and chronic fatigue syndrome — the differences and similarities?

If you step on a nail and have not had a tetanus shot in the last five years, how soon should a person be vaccinated? 24 hours? 48 hours?

I use Nalgene bottles for about 75 percent of the water I drink each day. Therefore, I was startled to find out that there is some possibility that these bottles leach chemicals into the water. I've found conflicting opinions about the veracity of these claims on the Internet. What's the truth? Should I dump my Nalgene for glass? You have an earlier post about bottled water, but it doesn't seem to address this issue specifically, and you recommend purchasing reusable bottles like the ones that might be poisoning me. The bottles I use have #7 on the bottom in the recycle symbol.

Why is your favorite food very tasteless when you have a cold?

I love sushi, sashimi, and oysters on the half shell. I apparently am uneducated (ignorant) when it comes to the health risks associated with eating raw seafood. I read in an article that a person could contract hepatitis A and worms. Is hepatitis A something that is "curable"? Are ANY of the diseases/problems associated with eating raw fish NOT "curable?"

After a night out with friends, I stopped in a nearby cafe before heading home to use the restroom. Unbeknownst to me, the staff had just mopped the restroom with bleach. Usually, a clean bathroom is a welcome amenity, but this one in particular is very small (barely a water closet) with zero ventilation. Though I was in there a brief time, my eyes and nose began to burn and water, and I could not very well open the door until it was time to wash my hands. It's been well over an hour since I inhaled all that bleach, and my eyes, nose, throat, and lungs all burn. I can't taste anything, and all I can smell is bleach. My head also hurts. I've gotten a lot of fresh air and plan to go back outside shortly, but these side effects have yet to abate. Am I in danger of respiratory damage? Is there anything specific to this situation I can do to alleviate the pain and discomfort?

Thanks for your help.
