At-home treatment options for arm pain, swelling, stiffness and cramps include rest, ice, compression and elevation. Additional home remedies include removing any rings, using a sling, gentle massage and avoiding tobacco use, according to WebMD.
Rest helps relieve stiffness and soreness in the arm muscles. It is also a good idea to cease any activity that causes pain, says WebMD. Applying ice or a cold pack to the painful area of the arm helps reduce swelling and pain. It is best to apply ice three or more times a day for 10 to 20 minutes. Additionally, for the first 48 hours after an injury, avoiding hot showers, hot tubs and alcohol prevents additional swelling. Elevating the arm to a level at or above the heart helps keep swelling to a minimum.
Wrapping the arm with an elastic bandage also helps decrease swelling as long as it is not too tight, advises WebMD. Numbness, tingling, increased pain and swelling below the wrapped area are signs that the bandage is too tight. The area should only remain wrapped for 48 to 72 hours. If pain persists after this time frame, the patient should contact a doctor.
Using a sling helps support the arm and increase comfort, states WebMD. Massaging the area encourages blood flow and alleviates pain.
