I cleared the head aches from my cleaner Clive. The secret is to apply High Intensity UltraSound to the affected area for 1 minute.
I use 8W 1MHz, from a medically licensed ultrasound massage device.
This can also be used to clear boils and all scin growths. No biochemistry. No trip to see the GP – now that GPs have read this little paper, they must all use this science, and stop prescribing defective biochemistry.
