The seroma may go away on its own within a few weeks or months. Your body slowly absorbs the fluid. No medicine will make it go away faster. But if you have a large seroma or if it's causing pain, your healthcare provider may drain it.

How long do seromas last?

Home remedies. Most seromas heal naturally. They are usually reabsorbed into the body within a month , although this can take up to a year. In more severe cases, it can take up to a year for them to be reabsorbed, or they can form a capsule and remain until they are removed surgically.

What happens if seroma is left untreated?

Small seromas often regress into the body on their own; those that remain can be aspirated using a needle and syringe. If a seroma persists, surgical removal may be considered. Large, untreated seromas pose an increased risk of infection, and they may develop a fibrous capsule, complicating drainage.
