Splint the injured area without trying to straighten the injured limb. Loosen the wrap around the splint if signs develop that indicate the wrap is too tight, such as numbness, tingling, increased pain, swelling, or cool skin below the wrap. A problem called compartment syndrome can develop.
If you do not have diabetes or peripheral arterial disease, a sore or sprained finger can be "buddy-taped" to the uninjured finger next to it. Protect the skin by putting some soft padding, such as felt or foam, between your fingers before you tape them together. The injured finger may need to be buddy-taped for 2 to 4 weeks to heal. If your injured finger hurts more after you have buddy-taped it, remove the tape. Then check your symptoms again. Caution: Never splint a finger in a completely straight position, such as on a Popsicle stick. For proper healing, the finger should be slightly bent and in a relaxed position.
