Question by Ack S.: The patient is receiving transcutaneous electrical nerve stimulation (TENS) for back pain. Describe how this m?
The patient is receiving transcutaneous electrical nerve stimulation (TENS) for back pain. Describe how this may work, based on the gate control theory.
Answer by scottsdalehigh64
The gating theory of pain regulation was created by Melzak and Wall. It states that the stimulation of large diameter nerve fibers (e.g., neurons carrying proprioceptive information) interferes with the sensation of information from small fibers (e.g., pain). This is the basis of TENS units, massage, and acupuncture. The larger diameter fibers are more sensitive to electrical and mechanical stimulation than are the smaller diameter fibers.
Howard Fields of UC San Francisco did an interesting experiment with respect to this gating mechanism. He found a group of Chinese patients in San Francisco who were to get dental work using acupuncture as anesthesia. In a controlled study, some of the patients received an injection of Naloxone (a drug used to treat patients who have taken an overdose of opiates), while other just got a control injection of saline. The test subjects did not get any pain relief from the acupuncture while the control subjects did get pain relief. This showed that the pain control mechanism of acupuncture (and presumably TEMS and massage) require the opiate receptors in the brain. That is, the traditional mechanism that acupuncturists believe (energy flows along meridians) is completely wrong.

Check out these upper foot pain images:
See, there’s this bandage on my nose…
Image by Ed Yourdon
I noticed this guy sitting on a bench at Broadway and 93rd Street, as I was walking back to 96th Street. I guess he had injured his nose, and maybe it was part of a larger injury that necessitated the use of a cane … but I wasn’t about to go ask him …
Note: this photo was published in a Jun 29, 2010 "Bandages 4 First Aid blog/, with the same title as the caption that I used on this Flickr page. It was also published in an undated (late Nov 2010) Back Pain blog , with the same title and detailed notes as what I had written on this Flickr page.
This is part of an evolving photo-project, which will probably continue throughout the summer of 2008, and perhaps beyond: a random collection of "interesting" people in a broad stretch of the Upper West Side of Manhattan — between 72nd Street and 104th Street, especially along Broadway and Amsterdam Avenue.
I don’t like to intrude on people’s privacy, so I normally use a telephoto lens in order to photograph them while they’re still 50-100 feet away from me; but that means I have to continue focusing my attention on the people and activities half a block away, rather than on what’s right in front of me.
I’ve also learned that, in many cases, the opportunities for an interesting picture are very fleeting — literally a matter of a couple of seconds, before the person(s) in question move on, turn away, or stop doing whatever was interesting. So I’ve learned to keep the camera switched on (which contradicts my traditional urge to conserve battery power), and not worry so much about zooming in for a perfectly-framed picture … after all, once the digital image is uploaded to my computer, it’s pretty trivial to crop out the parts unrelated to the main subject.
For the most part, I’ve deliberately avoided photographing bums, drunks, drunks, and crazy people. There are a few of them around, and they would certainly create some dramatic pictures; but they generally don’t want to be photographed, and I don’t want to feel like I’m taking advantage of them. I’m still looking for opportunities to take some "sympathetic" pictures of such people, which might inspire others to reach out and help them. We’ll see how it goes …
The only other thing I’ve noticed, thus far, is that while there are lots of interesting people to photograph, there are far, far, *far* more people who are *not* so interesting. They’re probably fine people, and they might even be more interesting than the ones I’ve photographed … but there was just nothing memorable about them.

A few nice webmd knee pain images I found:

I never realized the importance of wisdom teeth – actually, the importance of it not being there in your mouth. So I had the quizzical look on my face when my dentist recommended me to get them removed. Having gone through a lot of pain from the knee surgery, I didn’t think too much about getting them removed. Boy, was I proven wrong.
The one redeeming factor of the surgery was that I chose to get knocked out – that way, I didn’t have to endure the terrifying sounds of drilling going on inside your teeth (those who had it done that way will surely be able to recall that). I just remember some nice jazz piped into my ears and then waking up all loopy and trying to talk with a completely asleep lower jaw isn’t the easiest thing.
I felt some pain and discomfort (mainly at seeing cotton gauze being pulled out my mouth soaked blood red), but it was the eating part which confounded me for a while. I think the very first day, I just survived on banana milk-shake, icecream and yoghurt.
The pain, on the other hand, spiked up the next few days and my gums swelled up to match, leaving me with very little ability to talk, let alone concentrate on what I was trying to do. That certainly didn’t help when I wanted to go shooting near the Pigeon Point light house the very next day.
Somehow, I managed to get there and set up my camera to witness a rare colorful winter sunset…
Here is my take on it.
Shooting into the sun necessitated a HDR (didn’t have a reverse grad ND filter on me) with 4 exposures.

Question by Josh93: Chest pain on left side since being a child?
I’m 17 now and I have been having short pains in my chest for as long as I can remember. I’ve never told my mum or dad because I just ignore it but now I would like answers without going to the doctors if anybody as them. I read somewhere on the internet that it could be due to excess gas from the stomach/intestines.
The pains can last up too 4 hours.
Answer by Bob
i think you should talk to your doctor.
