After having anal sex with my partner, I noticed blood on him, although there was no sign of external damage. The next day I am feeling pain internally, but I can't pinpoint its location. What are the possible dangers and should I see a doctor?

1) Over the span of the last couple of years, I have noticed a significant number of moles appearing on my body. They have been appearing everywhere from my neck to my inner thighs. I had one on my neck since childhood, but now have so many more. Is this normal? Is it something I should be concerned with? And does child bearing have any relevance to this happening?

2) I have a mole which has turned very dark purple, and grown a bit in size (still small). This is the second time it has done this — last time was a couple of weeks ago, and it slowly faded back to almost nothing until today. Should I be very concerned about this?

I get cold sores around my mouth and nose all the time; I have since I can remember. I know that they can be caused by both physical illness and mental stress. Is there any way to reduce the frequency with which I get them, i.e., diet? Please help me, I feel like a leper.

I have had terrible stomach problems for a few years now. My doctor says it's due to my love of greasy and oily foods, and that I should concentrate on eating healthier, broiled foods. Do you think if I continue on this unhealthy eating cycle, that I could develop gallbladder problems? Also, do you think my diet contributes to my acne-prone skin? Thanks for your help.

I work ten-hour days, four-days-a-week, standing in one spot. The bottom of my feet feel like a lot of needles are pricking my soles. Could you please tell me what could be causing this? Just started about one month ago.

I am a first-year student and I want to get my nose pierced. This isn't just a whim; I've wanted one for a long time. However, I know that there will come a time when the ring will look juvenile on me. My question: will such a hole close up fairly quickly, without leaving an ugly scar?

As the summer is soon to arrive, I was wondering what type of clothing should I wear to protect myself from the sun? Also, what color works best, light or black? I seem to be getting conflicting answers on the Internet. I am a fair skinned male. Thanks for your help!

I was hoping to wear plugs. You know, the earrings...but do they hurt when you put them in?

What is wrong with my face? It permanently looks sunburnt across my nose, cheeks and on my chin. Sometimes it appears worse than others. It is hot to touch and often bleeds. Typical rosacea treatments do not improve the redness or pain. I'm overweight but otherwise healthy. Thanks!
