A digital prescription carrier and monitor system includes a pager sized carrier apparatus with an internal processor, a real-time clockcalendar, non-volatile memory, a communication port, a character display, and alert devices. The balloon defines at least two spaced larger diameter areas defining a valley therebetween and is adapted to be inserted in a non-inflated condition into a cavity of the human body such as the rectum, and when inflated, is adapted to cradle an organ such as the prostate located in a different body cavity. The second controller configures the second lookup table based on a mode determination. The system may switch the frequencies at a modulation frequency between 10 Hz and 10,000 Hz, between 50 Hz and 5,000 Hz, between 100 Hz and 2,000 Hz, or between other frequency ranges.
