1) This is sort of an embarrassing question...Recently I found out that there is something unusual just outside of my anus. It has grown like a pea. When I touch it, it is sort of hard but smooth, and it hurts a bit. What should I do? Is this like some kind of cancer?

2) I have this problem and I am too embarrassed to ask a doctor about it. I am a nineteen-year-old male and have this growth in my anus. It popped up about one week ago. It is about the size of a pea. Could it be hemorrhoids? If not, what can it be? Should I be worried, and what should I do about it?

I'm about to have rotator cuff surgery and repair some torn muscle. What natural healing foods can I eat to reduce the inflammation as well as increase the speed of healing of the muscle??

If I get hurt really sharply or suddenly, I end up passing out. This has happened once when I slammed my finger in a doorway, once when I bashed my elbow on the shower wall, once when my finger was held in an awkward, painful position, and once when I got a flu shot. Why do I pass out like this, and why do I have such low pain tolerance?

I was told by my dentist that my teeth eroded, due to consumption of too much acidic food. I would like to know what kind of food causes tooth erosion. Do you have a list of these foods?

I have a question about mumps: I had mumps while I was thirteen-years-old. I remembered that because of embarrassment. I was afraid to tell my parents about the inflammation (swelling of the testicles) at the same time I had mumps. I did not have treatment for the swelling of my testicles due to mumps. Later, the swelling went away about the same time as my mumps. Although I still can produce semen, I am deeply disturbed whether that swelling could have hindered my fertility (i.e., no production of sperm due to the blockage of the sperm channels).

I was having a conversation with my roommates about pop and coffee and we were wondering which is worse for your teeth, the pop or the coffee? And what do they do to your teeth when you drink them?

What causes fever blisters on lips and how should they be treated? Also, what is the difference between fever blisters and shingles?

Wondering if there are any negative effects to masturbation while being sick. I hear it could be a cause of lower immunity levels, is that true?

I just came here this fall. Since then, my nose has been bleeding occasionally without any injury. My friend told me it was because of the dry air of U.S. Is he right? How can I prevent this situation? I also have a problem when I brush my teeth. My gums are always bleeding and not just a little!! What should I do? Thanks.
