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?

Is it true that if you have the seed implant for prostate cancer, the patient can not come in contact with any pregnant women?

I have had Crohn's disease for 16 years and am in remission right now. Recently my boyfriend and I have been toying with the idea of anal sex, but I'm concerned about it given my health issues. I have a lot of thickening of the terminal ileum walls and worry that the "trauma" of anal sex could set off a flare up and be painful because of the narrowing. Any thoughts? I'm way too embarrassed to discuss this with my male doctor. Thanks!

Are there different sugar levels in different alcoholic beverages? I am hypoglycemic and have noticed different hangover levels contingent on the sugar level of alcohol consumed. Some have told me that Scotch has the least amount of sugar of all alcoholic beverages. Since I occasionally enjoy a drink, I would appreciate knowing the lowest sugar content.

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 have been a Type II diabetic for several years. I am now told I am beginning to show kidney insufficiency — is there a diet, or can you tell me where to find diet information of foods that a diabetic can use that are lower in protein and/or a renal diet?

I relocated to a new area within the past six months. Since then, I have been experiencing congestion in the morning and pressure in my sinus area, such as stuffed nose and difficulty breathing, at night when I lay on my back and in the morning. Although I do not have a cold, I seem to always have a small amount of drainage on a daily basis. Within the past week, I am sneezing quite a bit in the mornings and at night, my eyes are so itchy I can't help but rub them to a nice shade of red. I have never had allergies before, just for your info. Thanks for any tips.

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?
