Release your inner endorphins. Endorphins are the natural pain relievers produced by your body. They work by binding to the opioid receptors in your brain to block the perception of pain, similar to opioid pain medications, such as oxycodone or morphine. Spurring increased production of these natural hormones can substantially help reduce your pain, as well as produce profound feelings of pleasure and satisfaction.1
An essential nutrient available in certain foods (such as fortified milk and fish with small bones), vitamin D is produced naturally by the body during exposure to the sun's ultraviolet rays. But since it's difficult to obtain your recommended daily intake of D solely through dietary sources and sun exposure, many medical experts recommend increasing your vitamin D levels by taking a dietary supplement.
I use Tiger Balm ($5; It's kind of the old-school stalwart in the game. With active ingredients of menthol and camphor it can provide some relief to muscle aches, and has been studied to improve blood flow, especially when used during massage." — Joe Holder, S10 Training and Nike running coach (Reboot Your Workout Routine with Holder's moves that tap into every muscle.)

Various randomized, placebo-controlled studies comparing white willow bark with nonsteroidal agents have shown an efficacy comparable to these agents and aspirin. Salicin from white willow bark is converted to salicylic acid by the liver and is considered to have fewer side effects than aspirin. However, it is costlier than aspirin, and should not be used in children (to avoid the risk of Reye’s syndrome), or in patients with peptic ulcer disease, poorly controlled diabetes, hepatic or renal disorders, or other conditions in which aspirin would be contraindicated. The usual dose of white willow bark is 240 mg/day.[18,19,33,41,64,69,99,100]
The active ingredients in fish oil, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), enhance the conversion of COX to prostaglandin E3. A natural anti-inflammatory agent, prostaglandin E3 competitively inhibits the effects of the arachidonic acid conversion to prostaglandin E2, a highly inflammatory substance. Prostaglandin E3 also inhibits the synthesis of TNF-α and IL-1b, both of which are inflammatory cytokines. The EPA and DHA can inhibit the 5-LOX pathway, which converts arachidonic acid to inflammatory leukotrienes, by competitive inhibition as well. When EPA and DHA are incorporated into articular cartridge chondrocyte cell membranes, there is a dose-dependent decrease in the expression and activity of the proteoglycan-degrading aggrecanase enzymes.[12,23–25,27,50,85]
The first is that inflammation-lowering NSAIDs destroy your gut lining. Check the bottle of ibuprofen or aspirin in your medicine cabinet. You’ll see it right on the label: “NSAIDs such as ibuprofen may cause ulcers, bleeding, or holes in the stomach and/or intestine.”[1] Long-term low-dose aspirin use is particularly likely to cause ulcers and tear holes in your intestine.[2]
