2. Open the deep freeze
Apply a cold compress for the first day or two, and wrap with bandage if there’s swelling. One of the best cold compresses: a bag of frozen vegetables, such as peas. The bag conforms to the shape of your body. Hold the cold stuff on your achy body part for no more than 20 minutes. And give your aching muscles a rest for a few days too. The pain may get worse before it gets better, but if you’re still hurting after three or four days, see a doctor.
