Recovering from an arm or shoulder injury requires more that just some strong pain relievers. You've got to have the right equipment: the proper arm sling can make you feel more comfortable while it immobilizes your limb to help it rest and prevent further injury.
Sling Strap
The whole point of a sling is to keep your injured limb from moving, and a certain amount of comfort is essential while you recover. A good sling should be easy to put on without help: simple hook and loop styles are a good bet. You can simply slide your injured arm through the protective bandage, hook the strap on and loop it over your shoulder. You should also be able to adjust the strap if it causes neck fatigue.
Other styles have a comforting pad on the shoulder strap, or attach to the body around the back for maximum immobilization. In most cases, a doctor or medical professional will fit you for the sling; you simply repeat their fitting on your own.
Sling Body
The main body of the sling, sometimes known as a triangular bandage, should be soft and supportive. Other slings are segmented, focusing on holding specific parts of the arm in place, such as the wrist and elbow, without covering the rest. Some slings have thumb loops to let you use your hands; be sure to look for ambidextrous models for rightfree slings for those with allergies.
Size is determined largely by age; most are found in standard adult and children's sizes. Children's slings in particular come in colorful designs to comfort injured children. Those with frequent sports injuries or an especially active lifestyle should invest in supplies that allow for for long term use and future reuse. Look for something washable, in simple hues.
