Do you have a heating pad you can use instead?
I was told not to because of the methanol or whatever will soak into your skin and isn't good for baby
That's an iffy one. I would use bengay instead. I read as long as the icy hot doesn't contain methyl Salicylate, its ok to use.
My dr said I could use it on my back when it hurt. I'm sure its ok on shoulders.
