shiatzu and emotions - a question

i received a shiatzu massage today for the 2nd time.
the first time was very nice and made me feel very good.
i went to get a message as i have strong pains in my upper back and neck. and this was what the therapist was to work on as far as i know.
my question is: can it also intentionally or unintentionally release emotions? ever since i got the message i had a strong need to cry and my day turned into an emotional mess up to an anxiety attack - can it be as a side affect of the treatment?
and if so what am i to do now to return to somekind of balance so i will be able to function???
