Laugh more often. One study showed that social laughter actually increases pain tolerance.5 Laughing along with others was shown to have the highest positive impact. Laughter has many positive effects, including increasing circulation and oxygen, and raising your body's level of endorphins (the body's natural pain killers). There is a whole movement called "laughter yoga"—which helps people enjoy the many benefits of laughter without having to need a reason to laugh—it just focuses on laughing for its own sake.
Low back pain and neck pain often involve a substantial amount of muscle pain,22 and muscle pain is not particularly inflammatory by nature. Muscle knots (trigger points) are more like poisoned muscle than injured muscle. Although there’s some anecdotal evidence that taking an anti-inflammatory medication reduces muscle pain, mostly it doesn’t seem to work very well. One of the classic signs of low back pain powered by muscle, for instance, is that ibuprofen doesn’t have much effect!

Schematic showing another inflammatory pathway that is activated by tissue injury. This is the NF-kB activation, in which once the protein is free as a result of tissue injury, it can enter the cell nucleus and activate the DNA to enhance the inflammatory response further by the production of additional cytokines, chemokines, and adhesion molecules (IKKB = IkB kinase)
Traditional wisdom says that NSAID pain relievers only damage your gut lining if you take them every day for a long time, but recent research disagrees. High-level athletes with stress-related intestinal damage tried taking ibuprofen to improve muscle soreness and recovery. Ibuprofen ended up damaging their gut lining even further after just a couple weeks; it increased inflammation and made their original pain issues worse.[3] In fact, a single dose of aspirin can significantly increase your intestinal permeability.[4]
