I'm really stressed out because I've been getting recurring urinary tract infections coupled with yeast infections for the last six months. I'm not sexually active and I've been to two urologists and a gynecologist — they've all given me medication but the problems always turn up again. Is one problem causing the other? Can these prolonged problems be doing serious damage to my body? Perhaps you can't answer my questions either, but I'm really at my wit's end. What do I do? I'm tired of doctors and embarrassing exams and I can't understand why this is happening if I'm not having sex. Also, I'm a senior and in five weeks I'm out of health insurance — extending my parent's policy is very expensive and not an option. I'm busy trying to set up interviews, finish a thesis, and do a million things — I don't have time to be running around to more doctors' appointments! What insurance options are there for recent graduates?

This may sound like a dumb question... But I really am unsure. What is the difference between a milk allergy and lactose intolerance? Or are they one in the same? I was in an accident when I was 14. I had emergency surgery on my liver and spleen. After about the age of 20, I have developed severe mad dashes to the restroom after eating anything dairy.

But I have a lot of sinus allergies... that seem to flare up after eating milk products. Although generally milk products do cause thickening of the mucus... I was wondering if severe congestion also goes with it? I no longer eat milk products, of course. But I recently read about a child with a milk allergy who could not breathe through his nose afterward... accompanied by severe coughing. I am now 40 and learned my lesson well... But still curious and always looking for additional info and answers!!

I think I may have some kind of urinary tract infection. It came on very suddenly, about three nights ago. And when I pee, there is a burning sensation when my bladder has almost emptied. It's not an STD because I'm in a monogamous relationship, and yes, I'm sure! Please help. Thank you.

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!

I just was diagnosed with minor scoliosis. I am 38 years old (today!). I do yoga and while at a retreat, was told by the instructor that it looked like I had a little scoliosis on the right side. I crack my back, neck, and so on. I mainly do this on my right side (the side I have minor scoliosis). I feel very tight if I don't do it, and feel better afterwards, but I just know it's wrong. I don't know if my cracking my back is worse with this problem, or if I do it because of this problem. I have tried to stop, but even when I stop for a short period of time (month), my right shoulder "pops" (not snaps or cracks like when I do it intentionally while doing certain activities, like push ups or bench press (and it will happen over and over). This also occurs on my right hip when I do things, such as leg lifts. What do you think? Will this possibly go away if I stop or are they not related?

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.

Dear Alice,

I am seeing a guy I love and we are both thinking of consummating our relationship soon. We are both adults and this will be the first time for both of us. This is great, but also a bit scary in terms of the necessary protection.

How can having multiple sex partners be a risk factor for cervical cancer? What is the difference between having sex with one man one thousand times and sex with one thousand men (not that I'm planning to!) one time?
