Generalized swelling can be treated by resting the affected area as much as possible and elevating it above the level of the heart during times of relaxation, according to WebMD. It also helps to apply ice to the area, avoid eating to much sodium and remain hydrated with water.
Spending time in hot climates can exacerbate swelling, so WebMD recommends finding ways to cool down the skin to avoid this.
According to Neal M. Blitz, D.P.M., F.A.C.F.A.S. for Huffington Post, certain foods such as pineapples and capers contain beneficial enzymes that combat inflammation within the body and reduce any swelling associated with injury or surgery. If swelling is accompanied by pain, people can take over-the-counter nonsteroidal anti-inflammatory drugs, such as naproxen and ibuprofen. Acetaminophen and aspirin can also help to lessen any discomfort that occurs with swelling. Using more than one type of drug should be approved first by a doctor to avoid over-medicating a patient, especially when treating children.
WebMD warns against administering aspirin to people under the age of 20 without the supervision of a doctor. If swelling does not subside with rest, ice, elevation and pain medications, or is accompanied by fever, increased pain, difficulty urinating or breathing complications, WebMD recommends seeking medical assistance as soon as possible to avoid a possible emergency.
