What's the value of food sensitivity tests?

First of all I would like to thank you for your work and help. Could you tell me, what is the significance of expensive food sensitivity tests based on IgG values? Most people receive a list of dozens of foods to eliminate from their diets without causing them any problems. I think it can lead to develop eating disorders or nutrient deficiencies. What do you think? Thank you so much for your opinion!


How do tattoos work?

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?


What's TMJ and how can I get some relief?

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?


Where can I find basic information about emergency contraception?

1) My girlfriend and I had sex twice one night — the second time, we had to change condoms because she was dry and the lubricant had run out. Before I put the second condom on, she asked me to "put it in" without it on for a few seconds; which I did — not entirely all the way though. I instantly realized the mistake and withdrew. Naturally, as I expect, there is a small chance this could have gotten her pregnant. However, this was four days after her period ended, and the condoms we were using had nonoxynol-9 on the inside and outside. I had not ejaculated yet, as a matter of fact, I never did... and I had wiped the tip of my penis prior to doing this to avoid any pre-cum. My question is this: I'm hoping I'm right in assuming the chance of pregnancy is minimal — however, we are considering emergency contraception. What could you suggest?

2) My boyfriend and I had sex last night and we saw that the condom had broke. We don't know when it happened and I've been looking all over for the 72 hour correction thing that the commercials say — just in case. Can you help me?
