Hi! I have a question about heating pads. It says that people who are paralyzed, have circulation problems, are diabetic, etc...can't use them. Why not? What will happen?
Please explain this to me. I would appreciate it a lot!
Thank you!

It's because these people may have nerve damage, and so not realise when the heating pad gets too hot. This can lead to burn injuries.

My husband had a back injury. Before having his surgery, he used a heating pad. After a while, I noticed what looked like bruising all over his lower back. When he went to the doctor, he said it was from a heating pad. He was using it too much and at too high of a setting. After that he only used it 15/20 minutes at a time and only on medium. The bruised look went away in about a month.

Hi! Thank you for your answers! That is the reason I thought of, but, I wasn't sure.
Thank you!
