LM...I googled it and it costs too much compared to the risk of it not
helping.  I have serious perineal pain and discomfort (including hemorrhoids
along with prostatitis/urethritis) and I don't doubt the heat would provide
a *temporary relief* for pain and the increased blood flow may even help bph
patients.  I practically live with a heating pad on my belly and soak all
the time.

I would consider trying one of these (but not for 300-400 dollars), and I
doubt it would provide a cure for anything.  My understanding is heat
provides temporary relief for various conditions but does not cure them or
make them go away permanently.  This certainly applies to BPH [I don't think
its going to shrink your prostate :-)], as well as applying heat to a
herniated disc that is pinching a nerve is not going to get rid of back pain
either...Pete
