Hi Biobased,
How sweet of your sister!
I am glad you are starting to feel better.
The mat with the jade is interesting. I have only seen the biomats with amethyst. I did not try one, as the amethyst ones are quite expensive.
Cooked yourself an egg? Great! I could not stand long enough to cook this morning. I use a tall stool in the kitchen, if I am there very long. I was just in too much pain to stay in the kitchen at all this morning.
I have had good luck with rice-filled hot packs. They are so flexible and the heat so deeply penetrating.
I will do a search on the mat you have mentioned.
I hope you continue to feel better with each passing moment.
