I have a very tight pelvic floor and need to relax it. I want to start with 2 pads places on the ankle for tibial nerve stimulation. I was going to place one pad under the ankle bone and the other on the tibial nerve 2 inches above the other pad placement set back a bit from the other pad. Should I only use program number 11? Are there any other settings or programs I should use with external pad placements? Program 11 seems to be the only program that talks about pelvic floor relaxation. Thanks.
