Is neck and back cracking all it's cracked up to be?

1) I read the information on your website about knuckle cracking, and I was wondering if it applies to cracking backs and necks. I know that people often have their backs cracked by friends, etc. because it feels good and seems to relieve tension. Also, when my neck feels tight, I often turn it from side to side until it cracks and feels better. I've heard that chiropractors do some version of this, and call it "realignment." Is this safe? Is there a right or a wrong way to crack a back or neck? Is cracking your back/neck actually therapeutic in some way?

2) As a college student, I sometimes spend long hours reading books or looking at computer screens, and often my neck gets stiff. Like many of my joints that get stiff, sometimes I crack my neck, like I would crack my knees or fingers when they feel stiff. I often wind up doing this several times a day.

My question is, could I do irreparable damage to my spinal system if I continue using this method to soothe a stiff neck? Could I wind up a paraplegic if I continue to crack my neck? Leak spinal fluid, etc.?


How can I take care of my nails if I’m a chronic nail biter?

I am curious as to whether the nail bed regenerates or not. I used to bite my nails, and slowly I've bitten off some of the nail bed as well, on all ten fingers. It has been two years, and the nail bed does not seem to grow back, and my nails grow according to the new shape of the nail bed. It makes my hands look somewhat ugly, to be honest.

Any suggestions would be appreciated.


What are the symptoms of a heart attack?

1) I've heard that the symptoms for heart attack differ for men and women. Could you please send me info on these differences? Also could you give me some possible diagnosis for a feeling of heaviness in the chest?

2) Is it possible to have a heart attack without knowing you're having a heart attack?


Is stress causing my chest pain?

1) For the past year now, I have been getting sharp chest pains. Sometimes it feels like I am about to have a heart attack. I find it painful to breathe for the couple of seconds that it happens. The sharp pains occur mostly in the lung/heart area. However, I have also felt them in the lower chest area as well. I don't know what is causing this.

Also, it occurs most frequently during the school year. I should also note that during the school year, I tend to eat greasy fatty foods. However, I had my cholesterol level checked (95) which is low. These pains come any time of day, while I am sleeping, walking, sitting, etc. I am 21-year-old female, if that helps.

By the way, I have a doctor's appointment back home later this month. But I want to have an idea why this happening. Others mentioned to me things about stress, something about a dog's heart, and I was even thinking that it might be cancer.

2) I've recently been experiencing chest pains in the sternum area. Although I don't believe it is related to heart trouble, I think the pain is originating from the bones or muscles attached to the sternum. I have seen doctors but most are clueless as to where the pain may be specifically originating. An interesting side is that during times of stress, the pain is more severe and concentrated at specific points along the sternum. One hypothesis is that the pain may be related to an injured sterno-manubrial joint. If indeed this is the case, what therapy is available to a poor, uninsured student? My mental health is being affected since my once pumped-up, rock hard body is slowly atrophying since I can't lift weights without extreme pain. I'm depressed because the size of my chest is now smaller. What do I do? What's wrong with me?


Is it harmful to sleep on my side?

Is sleeping on our left side in any way harmful for the heart (or anything else)? Some people tell me we shouldn't do it and others tell me it's actually better than sleeping on our right side. What's the truth?

Thanks!


How do I manage unwanted hair growth as someone assigned female at birth?

1) I have a really embarrassing problem... I have hair on my chest and I am a woman! It's not really thick, but it's very noticeable, and I hate it! Is this a hormone problem or is it normal? Please help, 'cause to me, it's gross and I will do anything to get rid of it. I have been shaving it, but it just grows back within a few days or so. Please help!

2) I am a 24 year old female and for the past few years I have had facial hair. I tend to get it on my chin and the side of my face. It is usually light but you can feel it, and I will never let my boyfriend touch my face unless I have just shaved it.

I don't want to go for laser treatment, is their anything else you could suggest? I feel disgusting and very unwomanly.


Does a shampoo additive (sodium lauryl sulfate) cause cancer?

I was wondering about the chemical sodium laureth sulfate. I have received several forwarded e-mails about this causing cancer by a lawyer looking into the matter. This chemical was said to be in many shampoos to create a nice lather, but it's actually a garage cleaner and is a cheap substance for the manufacturer, and in the past, only 1 in 2000 would get cancer from this, and now it's about 1 in 10. I was just curious if it really causes cancer, or is it just a prank? And if it really does cause cancer, what kind of cancer is it? Thank you. I would appreciate an honest answer.
