10Ice
Applying ice is one of the most effective ways to deal with acute injuries, including upper arm pain. Low temperatures can help constrict blood vessels and reduce blood flow to the affected areas. This helps relieve inflammation and numbs your nerve fibers. You can apply this treatment 10 to 15 minutes each time. Do it several times during the day to get the best effects. Make sure to wrap ice in a thin towel or bag to prevent frostbite or irritation on the skin. [10]
