As I've blogged about before, I absolutely adore Icy Hot for muscle stiffness, but I've noticed something odd. When I apply Icy Hot to a joint, it makes the adjacent joint a wee bit stiffer.
For example, when I apply it to my shoulder, it makes my elbow a bit stiffer, in that I feel a little something in the elbow and I feel the need to crack it more. (And when I do crack it, it's louder). When I apply it to my knee, my snapping hip syndrome gets louder and I become aware of an old injury in the metatarsal area.
If it makes a difference, I have observed this when using the Icy Hot cream, as opposed to the patches. I haven't used the patches since I discovered the cream, so I can't tell you whether or not it also happens when I use the patches.
This atteinte of the adjacent joints is nearly negligible compared with the relief that Icy Hot brings me, but it's still very mysterious. Any thoughts?
