Dear Marianne, I've used my heating pad every waking , laid back position
for years. Never go to sleep with it on. I've actually burned myself with
Chinese heating packs. They have inconsistent ingredients, some are hotter
than others. You can put them under your clothes and walk around with them.
You look pregnant of course or marsupial at least. My General Practitioner
was more concerned with my skin burns (which seemed minor to me) than he was
my agony which was major to me. I've never had heating pads cause swelling.
Having said all this, everyone is different. I'm not a doctor. And I don't
know the answers, maybe it could even be bad for you, but it sure feels good.
Love and blessings, Sally
