I've been a good kid working out and being healthy, but the gym I go to has uniforms and I always wear a black t-shirt. That's great, until I sweat and it leaves salt rings where the sweat reached out to. Ewwww. This is embarrassing, and I have to wash the shirt before I can wear it again, which is annoying since I go almost every day and need to re-wear shirts once or twice. ANYWAYS, how can I reduce the amount of salt in my sweat, and prevent these embarrassing white rings from forming on my clothes? Eating differently, drinking more water, help!

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.

1) I'm a young gay man, and I'm concerned about oral sex and HIV. What are the risks, statistically and in your opinion, of receiving oral sex without a condom? Also, and this will sound kind of funny, I have braces, so I'm assuming giving head is dangerous.

2) A couple of weeks ago, my girlfriend and I were having oral sex and... well, to make a long story short, my penis got "snagged" on her braces and I received a deep cut on the head. I put Neosporin on it every night for a week, but the cut doesn't seem to be healing very quickly. I don't want to go to Health Services because of the embarrassing nature of the problem.

Help me quickly, please, because it also is very painful to urinate, let alone have any sexual activity. I was also wondering if there was a risk in contracting any STDs from this occurrence. I would really appreciate any advice you can give me.

I'm HIV positive, very low viral load & great t-cell count (not on meds). I've been reading recently that flu shots aren't all they're cracked up to be. What are the dangers of a flu shot, and if my immune system is already doing well, should I still get a flu shot?

After many years of confusion, I have been diagnosed with trimethylaminuria. It is an awful disease that has caused much emotional pain in my life. I was hoping that if the disease was discussed on your site that people's awareness may increase and perhaps people would not be quite so quick to judge others. I would appreciate it if you could post my message for this reason. Also, if the disease is caused by the lack of a certain hormone in my body, then would an injection of this hormone be a possible solution? In all of my research, I have not seen this discussed.
