Viddhakarma is described in the Sushruta Samhita as a para-surgical procedure where a specific body point is punctured using a fine, sterile instrument to relieve disease especially pain disorders.
Modern Interpretation
You can explain it like this:
1. Neurophysiological Effect
When a specific point is punctured:
Sensory nerve endings are stimulated
This activates pain-modulating pathways
Endorphins and serotonin are released
Pain signals are reduced (similar to the gate control theory)
This is comparable to procedures like:
Acupuncture
Dry needling
2.Vascular Effect 
The micro-puncture:
Improves local blood circulation
Reduces congestion and inflammation
Enhances oxygen supply to tissues
In Ayurvedic terms, this is described as removing Srotorodha (microchannel obstruction).
3.Functional Reset
In conditions like sciatica or joint pain:
It reduces nerve irritation
Relieves muscle spasm
Restores normal neuromuscular function
Ayurveda explains this as pacifying aggravated Vata.
