Why are we so sensitive to our body?

What freaks me out doesn't bother some?  My stomach ache means ulcer, my headache means tumor, my dizziness is high blood pressure, my rash is a major skin problem. My gas is a atomic bomb. You get the picture, what bothers me and causes anxiety doesn't even make another person with these problems blink an eye. Why why do we have to google, pop a benzo and spend the day sweating in fear, over something trivial? We know it's not major, but so what, it feel better to worry, and worry we do. Yesterday I went on a shopping trip to my favorite place, the goodwill. I can always find some great bargains and I usually love it, but not yesterday. As I was reaching to grab something off the top shelf my arms felt weak, and it felt like my blood pressure dropped, it scared me and I left. I have noticed before that my arms ache when I reach up, I must have a horrible disease, not long to live maybe? Or maybe.....I just need to work out my upper body and get more strenght and this is normal. 

I would be lying if I said I didn't do this from time to time still, but one thing a previous therpist taught me really stuck with me. If you have a symptom that is occurring for more than 3 weeks, then it's time to go get it checked out. So for example, a cough. The common cold/cough usually lasts for about 2 weeks. If by the 3rd week you are still not improving, then it's time to see your doctor. There are situations that certainly don't apply. After a surgical procedure I got cellulitis and it was spreading fast down my arm and I knew it was dangerous so that warranted a trip to the ER and 4 follow ups with my doctor. I think an important thing for people who think the way we do, it also to make sure we get annual physicals. If we're responsible and get checked out, chances are we aren't going to miss something when it happens.

The only one I really have trouble with is my heart. When it's racing and skipping beats, I think for sure something has to be wrong, even though the cardiologist has already told me that I'm absolutely fine.

Our minds and bodies due in fact play tricks on us. I read that Lucinda Basset book years ago and I remember her saying that panic attacks are our bodies playing tricks on us. Leading us to believe that we're in a state of emergency, when really that isn't the case. I try to remind myself of that when I'm having a panic attack and sometimes it works and others, not so much.

According to the book I am reading right now, Health anxiety body sensations and panic are a little different as in terms of cause.
Panic is sort of more momentarily feelings of doom and instant death, based on the pain/palpitations/breathlessness etc at that moment. So first bodily sensations come, then fear comes and goes after a while.
In health anxiety such body symptoms are mostly the creation of our long term fears of terminal diseases. For example, I am scared of breast cancer, and when I feel a tiny harmless sensation in my breast, then my mind makes it bigger and bigger until I feel more pain in this vicious circle. I just don't like to feel things and symptoms in my body. It makes me think the catastrophic way.

So it is quite hard to deal with, both of them in terms of anxiety.
We have the problem of paying too much attention to our bodily sensations, even sometimes make them up by ourselves, or imagine that it is a pain even though it's just a mere feeling of normal body issues like gas, etc.

Not really Deborah, I have to start soon though, in my last dr visit she said it's time for me to start yearly mammos. But well at least I gathered some courage to do the monthly self controls :/
Though, one has to have yearly mammos in anyways :P Scary...
