Whether you picked a too-heavy bowling ball in your Wednesday night bowling league, threw one too many baseballs with your kiddos or simply slept on your shoulder wrong, the TheraPearl Shoulder Wrap can provide you with the relief you need to get back to your busy life. Throw (not literally - you're hurt, remember?) your TheraPearl Shoulder Wrap in the freezer for cooling pain relief and to reduce swelling, or pop it in the microwave to feel immediate, penetrating heat.
