Actually, it's TRANSCUTANEOUS ELECTRIC NERVE STIMULATION.
It's NOT B.S., it's hugely effective!
It sends electric stimulation to/thru the nerves to block pain along the neural pathway, interupting the pain response message back to the brain to break the cyclic nature of the pain cycle. Normally, pain causes spasm, whih causes more pain, which causes more spasm.
TENS interupts this pain.
Many physical therapists use it almost exclusively. I've been using one for years and found that being able to hook up to the $40 home/portable version has been hugely helpful in that I don't have to take a pill or be dependent on someone else to decrease my pain. I can hook up and "bam" pains down from a 6 or 7 to a 2.
Although the concensus is: pain IS what the patient says it is.... we did some "research" and found it did NOT help malingerers and hypochondriacs 99% of the time .... tid-bit to think about.... do your research.
