It HURTS! Pain and the Brain part 1
Pain is weird. You only feel it in your brain… yet your brain has no pain receptors.
In part 1 of this 3-episode series, we unpack why pain is less a “signal” and more a decision your nervous system makes to feel it, shaped by reflexes, memory, mood, and context. You will learn why a hot stove makes you yank your foot back before you even feel anything, how “sharp” and “throbbing” travel on different nerve highways, and why chronic pain can become a disease of its own.
We discuss mind-bending paradoxes like phantom limb pain, referred pain (why heart attacks can hurt in your arm/jaw rather than your heart), and why two people with the same injury can rate pain totally differently.
