A recent study conducted by researchers at Georgia State University is the first of its kind to demonstrate that administration of preemptive morphine prior to a painful procedure in infancy blocks the long-term negative consequences of pain in adult rodents. These studies have serious implications for the way anesthetics and analgesics are administered to neonates prior to surgery. 
Unconscious Brain Still Registers Pain

Most of the time, doctors have a simple way to determine if a patient needs pain medication: They ask. But when a brain injury renders someone unable to respond to questions, the right course of action becomes murkier. Now a study finds that the brains of some patients with brain injuries respond to an unpleasant electrical shock much as do the brains of healthy people, suggesting that these patients may feel pain even though they're unable to show it
New Cannabis-like Drugs Could Block Pain Without Affecting Brain, Says Study

New research shows that CB2 receptors, a type of cannabis receptor, are present in the peripheral nervous system but not in the brain. The signficance? Now cannabinoid drugs that can be tweaked to affect only this receptor can be used for painkilling purposes without causing physical addiction or intoxication or any of the mild mental side effects know in recreational marijuana. Osteoarthritis in particular seems a likely place to apply this information.

Taking a popular class of pain relievers that includes aspirin and ibuprofen lowers the levels of a protein in a man's blood that doctors use to screen for prostate cancer, U.S. researchers said on Monday.
Cymbalta May Cut Chronic Low Back Pain

Cymbalta, a prescription drug used to treat depression, generalized anxiety disorder, diabetic nerve pain, and fibromyalgia, may ease chronic low back pain.
That's according to a study presented in Madrid at the twelfth congress of the European Federation of the Neurological Sciences.
The study included 236 adults with chronic low back pain who weren't depressed. They took Cymbalta or a placebo drug daily for thirteen weeks.
Average weekly pain scores, measured before taking Cymbalta or the placebo and again at the end of the study, showed greater improvement in the Cymbalta group
Anesthesia Can Cause Post-Op Pain

General anesthetics are used to put a patient to sleep during surgery, but new research has found that their use can increase the discomfort that patients feel when they wake up. The hope is that this scientific study, a first to explain anecdotal observations, could lead to increased use of general anesthetics that don't have this type of side effect or the development of a new kind of anesthetic
Why anaesthetics can make the pain worse

When you undergo surgery, you expect general anaesthetic to take the pain away, not make it worse. But new research suggests that many commonly used anaesthetics may worsen post-operative soreness and inflammation by activating peripheral pain pathways.
Is Aromatherapy actually good for you?

Researchers are reporting that two of the most commonly used scents in aromatherapy do nothing to heal wounds, relieve pain or enhance immune status, although one did briefly improve mood.
In fact, in some cases, distilled water showed more of a salutary effect, the study found.

A belief in the healing power of magnets has been around since ancient Greece, leading to a $5 billion a year worldwide industry that supplies millions of believers with magnets for everything from arthritis to cancer to depression. Researchers at the University of Virginia have found some evidence that the use of small magnetic fields may in fact affect blood flow.
Naked mole-rats don't feel the burn

Researchers have added to the list of biological curiosities about mole-rats: the animals do not feel all types of pain. The discovery could eventually help humans who are battling chronic discomfort.
'Painkiller' gene turned off in mice

Mice lacking a key protein took longer to react to a painful stimulus, prompting hopes for a new class of painkillers
Peptidase frees receptors in endosomes

“Internalized pain receptors are freed up by a peptidase for another round of agony, Padilla et al. reveal.
Peptidases on the cell surface cleave and thereby activate or inactivate small, extracellular peptides such as angiotensin. The enzymes also reside in internal compartments called endosomes, where their action is less apparent.
The new work shows that a peptidase called ECE-1 needs the low pH of the endosome to cleave several of its targets. One such peptide target was CGRP, which is released by cells during inflammation
Brain waves reveal intensity of pain
yangjane submitted, created time 1 year 2 weeks (www.nature.com)
Recordings from electrodes in the human brain may offer the first objective way to measure the intensity of pain.Researchers have found a neural signal that correlates with the amount of pain that an individual feels. The signal could be used to refine pain-relief techniques that involve stimulating the brain with electricity.
In the article, researchers tonud the relationship between pain and brain waves: The more pain that is experienced, the longer the waves last. Will the research reduce pain of patients?
Spinal Stem Cells Offer Hope Against Back Pain

For the first time, researchers have found stem cells within the intervertebral discs of the human spine.
They say it may someday be possible to use these stem cells to help repair degenerating discs in order to treat neck and lower back pain.
