@lakelady Yes! Ice machine and I had one of these things - https://www.polarproducts.com/polarshop/pc/Polar-Active-Ice-3-0-Broad-Coverage-Shoulder-Upper-Arm-Cold-Therapy-System-9-Quart-Cooling-Reservoir-p22962.htm got it from a medical supply store for cheaper than list. All you do is dump the water and put ice in there and it lasts a couple of hours. Circulates ice cold water over your shoulder.
