Depends on what you mean kinda fast.
...An acupressure technique is to press with thumb and forefinger the meaty part of your left hand between the thumb and forefinger...And hold for a minute.. This works for many headaches and can work quickly if it is not bad. Deep breathing also helps. Breathe in to count of 4. Hold 4. Out to count of 4. Hold 4...For as long as it takes to relax.
