It’s easy to tackle pain. There are shelves of prescription and non-prescription drugs that hunt down your body’s source of discomfort, and silence it. The most easily found painkillers come in the form of NSAIDs, or nonsteroidal anti-inflammatory drugs, such as ibuprofen. For some, this form of reducing swelling or alleviating soreness works just fine. But for others, the NSAIDs are tough on the stomach, or ineffective over a long period of time.
