A couple of months ago I developed a hard, bony growth on my instep. I noticed that the top of my foot was hurting, and when I took my shoe off, there was a red lump the size of a quarter (it's not red all the time, just from rubbing against the shoe). A friend of mine who is a nurse said that it's probably a ganglion cyst and the best thing to do would be to, and I quote, "hit it with something really hard," like a dictionary, or a hammer. It should break up immediately, she told me. She hasn't seen it, by the way — this was over the phone.

I'm surprised that she thinks it's a cyst, because it's awfully hard — I would have just thought that it was a bone spur. What do you think? And is smacking a cyst with a dictionary really the way to go?

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?

About six months ago, I experienced pain when urinating after having intercourse. Typically, I have pain/burning the first time I urinate after sex, but then the pain tends to go away or diminish. I am a 38-year-old male. I have no pain otherwise.

If a guy has jock itch, can it be passed on to a woman in the form of a yeast infection during sexual intercourse? I had intercourse with a guy and he had jock itch. A few days later I got a vaginal yeast infection. Could there be a connection?

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.

I just found out that a friend requires a kidney transplant. I've heard that we are all equipped with two kidneys and can live with just one. How do I find out if I can donate a kidney? What's involved in a kidney donation? Thanks!

What natural food or herb can help soothe stomach ulcers?

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?

The muscles in my back become extremely tense/tight throughout the term as I am cramped down studying all the time. What should I do?
