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.

I have a problem. I am a 21-year-old male with the face of a 15-year-old. What I mean is that I am unable to grow facial hair. I was late starting puberty and it has left me underdeveloped. My baby face is affecting people's trust in me, especially at my job. I am constantly referred to as the kid and I feel that I am never really taken seriously. I am wondering if there are any types of drugs that can possibly aid in my facial hair growth problem and, if there are, what are the side effects? Please help me. I am sick of being a man trapped behind a child's face. Thank you in advance.

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?

I have been a vegetarian for two years. Since last year, I have been losing quite a bit of hair. I have no pattern of male baldness in either side of my family. I do take multi-vitamins everyday. My diet is fairly nutritious. Could there be any correlation between my vegetarianism and the hair loss? Some books point to folic acid deficiency so I have made an effort to buy vitamins with 100%-200% RDA recommended folic acid. Do you have any ideas on what might be causing this?

I heard that eliminating or reducing red meat from your diet can help get rid of allergies. Is this true? Or just a rumor?

Does a virgin need to have a Pap smear? Is cervical cancer the only disease a Pap smear detects? What are the means of contracting cervical cancer and any other possible diseases detected by the Pap smear?
