Painful shock current range?

Explanation:
Painful shock begins when current through the body reaches a level that the nerves and muscles respond to with noticeable discomfort. Around 8 to 15 milliamps, the sensation typically becomes painful and you may also experience involuntary muscle responses or a strong tensing feeling. That makes this range the best match for “painful shock current.” To put it in context, about 1–2 mA is often just barely perceptible, 20–25 mA brings stronger sensation and more pronounced muscle reaction, and 100–200 mA can be dangerous, risking serious effects like ventricular fibrillation. So the 8–15 mA range specifically aligns with the onset of painful sensation in an electrical shock.
