Will I feel the stimulation?

Whether you feel the stimulation will depend upon both the amplitude of the current and whether the programmed therapy is "sub-perception" or "paresthesia-based." Therapy based upon the sub-perception paradigms are designed to not be felt, whereas paresthesia-based paradigms create a tingling sensation which is ideally matched to cover the normally painful area.

If the current amplitude is too low then you may not have optimal pain relief. If the amplitude is too high then you may have unwanted symptoms such as tingling or pain.
