When you accidently cut yourself with a very sharp blade like this ones for example... https://www.google.com/search?hl=en...urce=og&sa=N&tab=wi&ei=ywgBUZbmC9HMswbr64HYCg in the foot and there is bleeding, then why do you feel a very very sharp burning pain in the injured foot? http://p.twimg.com/A4u31JHCEAM06Bo.jpg:thumb
What I was taught is that when cells are injured ATP leaks out of the cell and readily binds to nerve endings causing the intense pain. This may also explain why the sharper the implement the less pain you feel because a sharper implement causes less trauma to the surrounding tissue therefore causing less ATP leakage and therefore less pain
I think I may be suffering from hyperalgesia or allodynia or something like that. I have an extreme fear of being cut and am quite insensitive to pain. http://juniorprof.wordpress.com/2008/07/05/what-is-hyperalgesia-what-is-allodynia/
Shouldn't it be the opposite? If you are insensitive to pain shouldn't you be less fearful of being hurt.
I've been told I have a low tolerance to pain, and that it saved me from a lot of grief when I had appendicitis. On a Saturday morning about 10:00am I started suffering a pain in my stomach area. As the day progressed the pain slowly intensified until by 11:00pm I knew there was no chance of my sleeping so I called a friend and had him take me to the the hospital. They put me on a morphine drip and the pain completely disappeared. The next day they did some tests and identified the problem and told me it hadn't burst yet and they removed it with no problems. I was told a lot of people with a high tolerance to pain hold out to long, before going to the hospital. After the appendix burst the whole process is a lot more life threatening and increases the potential for complications. In my case the pain was good and a little fear motivated me to take early action.
Sorry, my English is not so good. What I meant to say that I have an extreme fear of getting cut by something very sharp, like a sharp knife (for example) because I am very sensitive to pain.
What about oxygen? Maybe oxygen is responsible for the pain I feel after being cut after something sharp.
