I can't smell any odour from mine, but remember Parkinson's can damage your sense of smell!

Thatswhat I use on my neck bcs that is where most of my pain is,when I move my neck I can hear the bones cracking

Can buy from Amazon for £10. Or sew your own.

I have one and it is goo, I'd forgotten about it till it was mentioned. The only issue I have is my wife doesn't like the odour it can give off. But I can't smell any odour!! So I'm sure it's only in her mind! :):)

I like any safe source of heat to relax muscles and relieve pain. This sounds like a perfect product. My daughter teases me that my heating pad is my best friend and life partner. Smile! I have to admit, I do love that pad almost as much as my pup. I hope everyone finds relieve.
