Remember to wash your hands!
I have had good experience with warmth form the first use.  Only problem I had was after applying it to my thumb on the first day, I didn't wash my hands after thirty minutes and I touched my face near my ear.  It was only a little heat but enough to remind me to be careful.  I am starting to have less arthritis pain each day.  I will continue to use the pain bloc.
