I tried posting a similar message a couple days ago, I'll try again:

I've read about heat methods and Vogeli's experiments. Is a heating
pad a suitable replacement for hot water. It's difficult to maintain
water temperatures and sit in a tub for 45 minutes a night for two
weeks. Are there any dangers with a heating pad besides the obvious
burning or scalding, etc. How long do you need to apply the heat per
session and how many days. Also when will the results take place.
Is it a month after you end the treatment or immediate. I know it's
not foolproof but it sounds like a good alternative. Thank you
