Most causes of back pain don't require immediate medical attention, but you should see a doctor right away if your pain is accompanied by any of these "red flags": • Weakness or pain in your legs, especially if it goes all the way down to your feet. • Loss of bladder or bowel control. • Fever or tenderness. The first two could be a sign of neurological damage, caused by compression of the nerve roots at the lower end of the spinal cord. A fever or tenderness may signal an infection.

A venomous bark scorpion, its stinger poised to strike, confronts a furry, little grasshopper mouse somewhere in the desert. A deadly melee is about to begin and you won't believe who wins. Even though the bark scorpion possesses one of the most painful -- and potentially lethal -- stings in the animal kingdom, he's about to become lunch for a twitchy little rodent. Thanks to evolution, the grasshopper mouse no longer feels the intense burning, and subsequent throbbing, that humans or other mice feel when injected with scorpion venom -- pain that would stop most predators dead in their tracks. In fact, after several stings to the face, a grasshopper mouse stops briefly to groom itself, then resumes its savage attack before feasting on the overwhelmed scorpion.

When Rebecca Soni took down one of the hallowed barriers in swimming - becoming the first woman to go under 2 minutes and 20 seconds in the 200-meter breaststroke - the moment resonated on multiple levels. Not only did her star turn come on the world stage, at the London Olympics, the modest Soni became the first American swimmer to repeat a gold-medal performance in the breaststroke, winning in 2:19.59. Four years prior, Soni upset the heavily favored Leisel Jones of Australia to own the podium at the Beijing Olympics in the 200 breaststroke.

Across cultures and language divides, people talk about the sting of social rejection as if it were a physical pain. We feel "burned" by a partner's infidelity, "wounded" by a friend's harsh words, "crushed" when a loved one fails us, "heartache" when spurned by a lover. There's a reason for that linguistic conflation, says a growing community of pain researchers: In our brains too, physical and social pain share much the same neural circuitry. In many ways, in fact, your brain may scarcely make a distinction between a verbal and physical insult.

Ash Wednesday marks a day of sacrifice and penance for Christians in order to atone for sins. The theology of the idea coincides nicely with psychology. Feeling pain, it seems, really cleanses the mind of guilty burdens, according to a new study. Australian researchers tested the idea of whether pain and sacrifice ease guilt. They recruited 62 young men and women under the guise that they were part of a study on mental and physical acuity. The participants were asked to write a short essay about a time when they had ostracized someone.

Pain is private. Unlike blood pressure or temperature or other symptoms easily measured and defined, the physical reaction to unpleasant stimuli is hard to quantify or predict. It varies from person to person, with each individual describing pain — and its intensity — differently. But that private perception can make the difference between a trip to the medicine cabinet for an aspirin or a trip to the doctor's office for something much stronger. Researchers study pain not to separate whiners from stoics but to understand why pain varies and, eventually, create individually tailored treatments for the many specific ailments that fall under the umbrella of pain.

Lindsey Vonn has been released from a Vail, Colo., hospital after undergoing testing and treatment for intestinal pain. Vonn's spokesman, Lewis Kay, wrote in an email to the Associated Press that the four-time World Cup ski champion was "resting comfortably at home" and that she's "feeling much better" after an overnight stay in the hospital. Kay said it is unclear when Vonn "will be able to return to the mountain” as she prepares for a World Cup event in Aspen on Nov. 24. There has been concern in Vonn's camp regarding her ailment, the cause of which doctors have been unable to determine, according to Kay. Vonn's ski technician, Heinz Haemmerle, said Vonn's recent trip to the hospital was not her first in recent weeks.

OK, enough talk about Lance Armstrong and his possible use of drugs or blood doping as a performance enhancer. It turns out some athletes in the Paralympics, which begins Wednesday in London, use pain as a performance enhancer. Paralympics officials said Monday that, along with testing for banned drugs, they will be on the lookout for something called "boosting" among wheelchair athletes. What is boosting? Pain. In able-bodied athletes, physical exercise raises the heart rate and blood pressure, which helps you perform better during an event.

OH, your achin' back. It can happen lifting something heavy, or simply reaching for a book. About 85% of adults suffer low back pain at some point in their lives. For most, the pain resolves in a few weeks. For others, it can be long lasting and difficult to treat. Now researchers have found a way to help identify the approximately 20% of back pain patients who might be helped by facet joint injections.

Adrian Gonzalez said on Monday that he intends to play through the discomfort in his neck. The MRI exam Gonzalez underwent earlier in the day revealed a strained neck muscle and nothing more, according to the first baseman. Gonzalez is in the lineup for the Dodgers' series opener against the Arizona Diamondbacks at Dodger Stadium. “Basically, it's how much pain you can tolerate,” Gonzalez said. “I'm going to try to play through it and see how it feels when I'm out there running around and doing all those things.” Gonzalez was injured when he collided with an umpire on Wednesday.
