painfull bladder

hi, i'm 32 years old. AND in the last two monthes i'm suffering most of the time from pains in my urine bladder. from all tests i've done nothing found to explain it. I went to an acupenture AND he put one needle one sentimeter from the pubis bone , is that can be harmfull? p.s. me AND my computer can read hebrew, it just can't write)
