I've noticed what appears to be a wrist bone protruding on the back of my right hand. It's on the thumb side and closest to my forearm bones. I've been playing a lot of golf lately, and someone told me it was a "golf nodule." If so, what are golf nodules? Is this dangerous (it doesn't hurt right now), and do I need to do anything about it?

Please help! My skin is drying out like you would never believe. It is scaly and itchy at times. Could this be as a result of the weather? Are there any pointers that you could give me so that I don't feel like my face is cracking and looking like garbage? It seems to get worse after I shower. What is this? What can I do?

Do men need to cover up their testicles when using indoor tanning facilities?

I use tanning booths regularly and I normally use only eye protection. I am slightly worried, however, that the UV radiation from the sunlamps could do internal damage to a man's testicles, because the skin is obviously only very thin and might not offer much protection against UV radiation. Since eyelids are similarly thin and it is known that eye damage can result even when using tanning equipment with closed eyes, I wonder if advice should be given to men to use similar precautions to prevent testicles being exposed to high-intensity UV-A or UV-B radiation. I have looked everywhere for scientific information on this matter but could not find anything. Your advice on this matter would therefore be very much appreciated.

I read that disposable contact lenses are actually worse for your eyes than the normal one-year ones because they allow less oxygen to go to your eyes, and the only advantage is that there are less cleansing problems. Also, it is claimed that inadequate oxygen to your eyes (possibly caused by prolonged wearing of contact lenses) leads to a condition when extra blood vessels sprout around the iris, which leads to sight problems at old age. Is that true?

I am very concerned because I normally wear (one-year) contact lenses from 8am to 8pm, and maybe to 12am during reading periods. I don't feel very comfortable with glasses because they give distorted visions and fatigue. I thought switching to disposable contact lenses would do my eyes good. My current lenses contain 38 percent water. Is this good enough?

I recently started taking birth control pills to help with my acne. But since it is considered a low dosage kind (Low Ogestrel, to be specific), I wonder if it is still an effective and safe contraceptive. Can I take this kind and not have to worry about getting pregnant?

A friend of a friend told me all about this ultraviolet/blacklight tattoo method. It was deemed unsafe earlier when it first came out, but apparently now it is completely safe. This friend of a friend said she does these tattoos all the time now and is really good about not scarring. So I'm not worried about anything like scarring being seen, I'm just worried about getting cancer and other accusations when ultraviolet tattoo first came out.

When I was young, I had no freckles. As I got older, my face began to form freckles. Also, darker freckles are forming. Is there a way I can remove the freckles or stop them from forming?

In a recent question about abnormal hair-growth, the writer mentioned a long history of hydrocortisone use as a means of treating eczema. I too have a long history of severely uncomfortable and troubling eczema. During the worst outbreaks, I have visited several different dermatologists, and all have prescribed topical hydrocortisones, such as Hytone or Topicort, as well as anti-itching pills, such as Atarax. One prescribed Diprolene ointment, which I used for a year, until my next dermatologist dismissively told me it was far too strong and could be damaging.

I would like to know once and for all how damaging the extensive and long-term use of any of these creams is. Please give me one of your straightforward answers; I have been frustrated by the differing views and lack of concern among the dermatologists I have visited. I am tired of being told it is "just eczema." I already use the gentlest cleansing products available, tons of moisturizing cream, rinse all my clothes twice, wear soft fabrics, etc. I am still absolutely tortured by itching, often resorting to scratching at my skin with a hairbrush. The eczema reappears without fail in the same places, even on my face, and is particularly bad after stress periods, when I absolutely cannot control my itching or scratching. Isn't there anyone anywhere doing research on this? Is there anything else I can try? I am not averse to vitamin, holistic, or homeopathic therapies, if there are any. Please help. This is really a very ugly and upsetting problem.

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?
