Pain, it can be acute or chronic, sharp dull throbbing or burning. It can be physical or
emotional, even phantom. Just seeing pain in others can causes distress, but what is pain,
why does it affect us, why is it so difficult to treat, how much is actual discomfort, and
how much is in our minds?

To find out, I'm heading to London's Dana Center where you eat, drink, socialize and learn
in an atmosphere that's both relaxing and unintimidating. Science in the news and on the
cutting edge has discussed with experts. Most events are free. Tonight's event in pursuit of
pain is organized by Elaine Snell.

The Dana Center is part of Science Museum and where is the Science Museum has gone for this
Fabulous,only forwonderful items and exhibits. There isn't touch your place to talk. More
and more issues are coming out now in medicine and science. Well, we actually have to kind
of make quite an important life choices things like stem cells and genetics. So er, this is
how the Dana Center came about, if we want to break down all the barriers, we want the
speakers to be in the most audience and relax that atmosphere very informal. And for that to
be a real dialogue.

Back to, pain.

In a nutshell, what, what is pain?

Pain is whatever you want clearly. It is quite difficult to come to fight pain.
How much of pain is, is in your head?

Some of this, some of this / in your head, not seen, most of it is because you are in pain
and you know the reasons for the pain. I think most difficult pain to explain is where you
haven't injured yourself there's obviously nothing wrong with you, but you are in pain.
That's neurogenic pain, / because your nerve system is misbehaving in some way and producing
pain sensations.

What about the type?
Er, phantom pain, meaning people with with missing limb to their hand hurts,
but they don't physically have a hand there, I mean, how, what, is this a similar type of
pain?

We still have a map in your body of where all things are, so people who've lost their legs
can still feel pain in the missing leg, in the missing toe and say it's really painful there
because the central nerve system only has a map with the, the leg still there even though
it's missing.

With so many variations of pain, how do you treat it? There are a number of traditional
medical remedies and more are being developed every day. However, many people are looking to
alternative therapies to treat pain.

How does acupuncture help pain?

By medical sets, and they took about acupuncture, blocking certainly nerve pathways. Oh, the
pathways which are responsible for transporting pain to the brain. So they are actively
blocked by the acupuncture stimulate and there's another theory where by, um, giving /
acupuncture to our patients. Eventually it's to release of more thing like chemicals in the brain which also, kill pain and that's a nice very powerful painkiller.

Maggie Heywood deals with chronic bad pain every day. But here could be an answer. Michael
H, from University College London, presents his research into using plants to treat pain. He
is paving the way to use plants such as cannabis and devil's claw to alleviate various types
of pain.

My daughter is a student nurse, and we felt that this talk tonight was deeply appropriate.

I've seen people first time to appreciate the pain, so um, you have just wanna know how to
treat really.

It is a valuable aspect of human body, I think it's also on that, if you don't have pain, you are in trouble. We need pain.
