SUMMARY

Post-micturition convulsion syndrome (PMCS) is characterized by a shiver along the spine experienced predominantly by males after urination. This phenomenon is described as a vigorous shivering rather than a full-body convulsion, and it is classified as a normal physiological response. The exact cause of PMCS remains unknown, with theories ranging from sudden thermal deficits to parasympathetic reflexes. The term "convulsion" is misleading, as it does not relate to epileptiform fits.

PREREQUISITES
  • Understanding of physiological responses in humans
  • Basic knowledge of the autonomic nervous system
  • Familiarity with thermal regulation in the body
  • Awareness of common male physiological phenomena
NEXT STEPS
  • Research the autonomic nervous system's role in physiological responses
  • Explore theories related to thermal regulation and its effects on the body
  • Investigate other physiological phenomena similar to PMCS
  • Study the implications of reflex actions in human physiology
USEFUL FOR

Medical professionals, physiologists, and individuals interested in human physiological responses, particularly those focusing on male health issues.

Post-micturition convulsion syndrome, I read, is a shiver felt along the spine, mostly in males, after urinating. For my life, I have had a post-micturition convulsion syndrome, but it isn't just a spine shiver, I find it to be almost violent "shivering," not quite full body, but more than just the extremities. How personal. So, what's up? Do I fit into this category, or is it something else?

It's a misnomer (of course), "convulsion" brings to mind epileptiform fits which have a (presumably) completely different etiology. This is a thermostasis/rigor-type muscular shiver.

This physiological (meaning normal) phenomenon is fairly common and the reason for it is basically unknown. As the straight dope article said, various theories have been put forward from a sudden thermal deficit to a parasympathetic reflex. In other words, we don't know piss about it. :biggrin:
