Designed to aid those with hand pain, the Elasto-Gel Hot/Cold Therapy Mitten helps with both acute and chronic pain. Conveniently shaped like a mitten, the hot/cold pack bathes the hand with soothing relief. To treat acute hand pain, use the Elasto-Gel Mitten as cold therapy (crypto therapy). The cold pack will reduce the swelling and inflammation, meaning less pain. The Elasto-Gel Mitten can be used in cold treatments for 20-40 minutes per application. When not in use, the mitten can be stored in the freezer indefinitely. The Elasto-Gel will remain flexible even at -20 F. To help with chronic hand aches, utilize the Elasto-Gel as moist heat therapy. The heat increases blood flow, relaxes stiff muscles and melts away soreness. The mitten can be warmed-up in either a microwave or conventional oven.
