It’s been a good day; good but demanding, and now you’re a bit stiff and sore.
The advice by everyone from your mom to your high school track coach to your doctor rings in your ears: Put some ice on it. In your truck, that can be easier said than done.
Often, improvised ice packs slip off or leak. Truck stop bags of ice are too big.
Then there are Paincakes, which are 5-inch round reusable ice packs that use medical-grade adhesive to stick onto your sore back or hip or shoulder or calf. Not only do they deliver the cold where it’s needed, they do so conveniently.
