Is the lump behind my knee a cyst?

I have a one half inch lump inside the back of my leg two inches above my knee (there is no visible mark on the skin). It is not painful or bothersome in any way. An acupuncturist thinks it is a cyst. If it is, what kind might it be, what kind of treatment might I get, and how necessary is it?


Does eating ice correct an iron deficiency?

My sister has been told by one doctor that eating ice is effective for an iron deficiency. Another doctor says that this is balderdash and not effective.

What is the deal? Which opinion is correct? Why is there no consensus on the feedback physicians give for this subject?

I also would like pointers to more information for this topic.

Thanks.


Why do people find fatty or sugary foods comforting?

Why do people find fatty or sugary foods comforting? I mean, what is it in these types of foods that causes the body / mind to see this type of food as comforting or pleasurable? Surely from the point of view of the body, it prefers foods that are high in nutrients — so why do people who turn to food for comfort always turn to fatty or sugary foods that don't offer the body anything? just wondering??? and I hope that made sense because I'm sorry it's quite badly worded!


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.?


Do diet sodas spike insulin levels?

I have heard that the main reason why diet drinks, like a diet soda, can be bad on a diet, is that it can spike insulin levels and then your body expects sugar that it does not get. I have taken to the habit of only occasionally having diet drinks with meals, so that any increase in insulin is actually met with food in my system. My question is whether or not this is a good/workable strategy, or whether a diet soda is a diet soda no matter when you drink it and is therefore always a bad idea. Thank you for your time.


Are there any nutritional benefits to swallowing semen?

1) I'm worried. What happens if you eat your own sperm?

2) Today a girlfriend and I were discussing the nutritional value of sperm. While performing oral sex, if you swallow, I was told that it is very high in protein. However, I was also informed that it is very high in calories. This may seem like a weird question, but I would like to know what nutritional benefits are involved when "swallowing" and how many approximate calories are in a man's ejaculation? Thank you for your help in this matter.


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?
