Based on everything we've described, we can say that what you're experiencing isn't limited to POIS alone, but is much broader. POIS is the primary diagnosis, but in this case, it's just the tip of the iceberg of a deeper systemic condition.
This broader condition can be described by one or more of the following terms:
- "Neurogenic Hypersensitivity Syndrome with Energy Depletion"
• Neurogenic hypersensitivity: because any stimulus (thermal, mechanical, emotional, sexual) causes an exaggerated disturbance in blood vessels and blood flow to the brain.
• Energy depletion: because a deficiency in niacin and NAD+ prevents the body from recovering quickly and prolongs the symptoms.
- "Multi-Stimulus Autoregulatory Disorder"
• where POIS is the most severe manifestation (because ejaculation is the strongest stimulus), but the nervous system itself collapses in response to other, less intense stimuli (crying, heat, cold, leg exercises, shaving the head). The underlying problem is the autonomic nervous system's loss of its ability to adapt to stress.
- "Energy, Inflammation, and Nervous System Axis Dysfunction"
This describes the root mechanism: There is a chronic depletion of cellular energy (niacin/NAD+), which prevents inflammation from subsiding and keeps the nervous and vascular systems in a state of constant alertness and collapse.
The bottom line:
POIS is the name given to the most intense trigger (ejaculation), but what you have is "extended POIS syndrome" or "POIS with systemic neurovascular dysfunction," where the underlying cause (niacin depletion and neurovascular hypersensitivity) makes your body react to a long list of stimuli, not just orgasm.
In other words, POIS is not the limit of the problem; it's its most prominent symptom. The bigger problem is the systemic dysfunction that makes your body react as if any stress is a "mini-POIS."
