Part two of this Science Savvy pain series explains how common painkillers work, why many provide limited relief, and how pain is shaped by nerves, the spinal cord, the brain, and emotion!! (emotion?!?!)... we even talk about porn, sexual arousal, and its impact on pain... the ffff
The episode covers common drugs like ibuprofen, paracetamol, local anesthetics (at your dentist office) through to not-so-common drugs like opioids. We also talk about why expectations, social support, and non-drug approaches matter - a little bit of hope man, please.
