All panadol(equal) products, works by "cutting" a hole somewhere
in ur tummy area(u won't feel the pain). The brain will detect
there is a cut and focus on the area and "forget" your current
pains(headache, tummy etc) for a period of time. Which most likely
your old pains will lessen or auto-recovery by itself when the
effect of panado wears off.
