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 plan to do some nude sunbathing this summer. What extra precautions should I take with the areas that have never seen the light of day? Should I use a higher SPF on my "naughty parts" than on, say, my arms and legs?
