How do you treat swelling forehead?

To treat swelling on the forehead, first, apply a cold compress or ice pack wrapped in a cloth for 15-20 minutes to reduce inflammation. Over-the-counter pain relievers like ibuprofen or acetaminophen can help alleviate discomfort. If the swelling is due to an injury, monitor for signs of a concussion and consider seeking medical attention if symptoms worsen or do not improve. Additionally, if the swelling is due to an allergic reaction or infection, consult a healthcare professional for appropriate treatment.
