Desc-Cysts by DTownTony | May 14, 2023 × Cysts are small sacs or bumps that can appear on the skin and are often filled with fluid or other material. They can be found anywhere on the body and vary in size and shape. Cysts are usually painless and harmless but can become infected or inflamed, causing discomfort or irritation. In some cases, a dermatologist may need to remove a cyst to prevent infection or for cosmetic reasons. It is important to seek medical attention if a cyst becomes painful, inflamed, or changes in appearance.
