What is the effect of ice to a bump?

Ice can be an effective treatment for minor bumps and bruises, helping to reduce swelling and pain. When ice is applied to the affected area, it causes the blood vessels to constrict, which in turn reduces blood flow and swelling. The cold temperature also helps to numb the area and reduce pain. To use ice for a bump, simply apply a cold pack or ice wrapped in a cloth to the affected area for 15-20 minutes at a time, several times a day. Be sure to avoid applying ice directly to the skin, as this can cause damage. If the bump is severe or does not improve with ice treatment, it is important to see a doctor for further evaluation and treatment.
