Rest and ice are two ways to treat upper-arm pain, states WebMD. Taking a break from activities or changing motions that cause pain in the upper arm is recommended. Applying cold packs or ice reduces swelling and pain.
Refrain from activities that cause pain in the upper arm, as these activities could be the cause of the pain, notes WebMD. Rest the stiff and sore upper-arm area by elevating the arm whenever able. Use cold compresses or ice packs for 10 to 20 minutes three or four times a day, avoiding hot showers or hot packs the first 48 hours. After 48 to 72 hours, apply moist heat packs and cautiously begin exercising. Alternate heat compresses and cold pack treatments to the upper arm to help restore and maintain flexibility.
Wrapping the painful area with an elastic bandage helps reduce any swelling, explains WebMD. Be sure not to wrap the arm too tight as this causes numbness, tingling and increased pain. If a wrap is needed for more than 48 to 72 hours, consult a physician for diagnosis and treatment. Remove any jewelry or watches to avoid constriction of blood flow. Wear a sling if it helps with discomfort and pain.
