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!


Why am I having trouble ejaculating?

1) I am a 20 year old male. My problem is that I have never ejaculated. I have no problem getting and maintaining an erection, but it seems as though I cannot ejaculate. If I masturbate for about ten minutes, my toes begin to become numb at a peak time. I have had several wet dreams, which I assume are semen. I also read an article where when passing a bowel movement, sometimes semen can come out of the penis. This happens for me as well. Do I have a serious problem? Eventually, I want to have children, and I am wondering if this could stop that. Thank You.

2) I don't know what to do! My boyfriend has no trouble becoming sexually aroused around me, but when we try to have sex, he just doesn't seem to be able to actually have an orgasm and ejaculate. He only has had one with hand stimulation when hand cream is involved, but not otherwise. Oral sex does not even work. This is very frustrating; he tells me it's his fault but I feel like it's mine. Plus, he says he didn't have as much trouble with his past girlfriends, but that he cares about me so much more than them. I'm really confused. Is there anything either one of us can do?


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?
