Assuming you can get past the fact that this looks like a small anvil, this device could potentially work - so they claim that is.

The hand-held device creates a short-lived electromagnetic field which ‘interrupts’ the migraine.

At the American Headache Society meeting researchers said the device was effective in treating nausea, noise and light sensitivity.

UK experts said the findings were interesting but warned it needed to be tested in a much larger study.

People who suffer from migraine headaches often describe seeing showers of shooting stars, zigzagging lines and flashing lights, and experiencing loss of vision, weakness, tingling or confusion.

These neural disturbances or ‘auras’ signal the onset of migraine headaches.

The device, called TMS, delivers a strong electric current through a metal coil, which creates an intense magnetic field for about one millisecond.

The theory is that the electrical charge interrupts the aura phase of the migraine before it leads to headaches. … Source: BBC
