Most lumps and swellings under the skin are harmless and can be left alone, but should be checked by a GP so the cause is known.
In general, a painful lump or swelling that appears suddenly over a day or two is usually caused by an injury or infection. It’s likely to be an infection if the skin around the lump is red and warm. Dr Yip can advise you how to care for this.

- neck or throat
