I've seen used swimsuits on Ebay and in thrift stores. I've also heard that buying used is a great way to save money and prevent waste. I'm not sure if a wearing someone else's swimsuit is a good idea, even if I were to I wash it in hot, soapy water. Is it hygienic to buy used swimsuits?

I was wondering what I personally can do (habits, diets, activities) to strengthen my immune system? Thank you!

Does a virgin need to have a Pap smear? Is cervical cancer the only disease a Pap smear detects? What are the means of contracting cervical cancer and any other possible diseases detected by the Pap smear?

Seems like the only health risks you read about in the news is from eating tainted fish or from getting an infection when swimming in the ocean. Are there other direct effects on our health posed by pollution in the ocean?

I read the info on molluscum in the Men's Health section. Are there any signs that distinguish molluscum from genital warts/any way to tell if you have one or the other?

How do tattoos work? I mean, if human skin cells are always shedding and reproducing themselves, how are the pigments of a tattoo able to stay in the skin for so long?

1) What is TMJ? What kind of doctor handles this problem?

2) I have a rather odd problem. For the past several years, I have noticed that when I open my mouth wide to yawn or take a bite out of a sandwich, the right condyle of my jawbone slips laterally from the temporomandibular joint, making it difficult, and at times, painful, to close my mouth. I basically have to slip the condyle back into the socket; otherwise, it slips in by itself, which is what causes the pain.

Other than being inconvenient, this has not adversely affected me in any way that I can tell, except that I am now careful not to open my mouth completely when I yawn. I am reluctant to see a doctor about this because I cannot reproduce the situation at will, and don't know if the problem can be diagnosed or detected unless the doctor actually sees the condyle slip out.

Also, any time I have gone to Health Services, it seems that whatever the problem, they just send me home with a jar full of ibuprofen. What do you think is wrong? Is this problem serious? Does it deserve immediate attention? What type of doctor would I need to see and could I get a referral from Health Services?
