Do cysts go bigger and smaller?
Cysts can range in size from smaller than a pea to a few centimetres across. They grow slowly. Skin cysts do not usually hurt, but can become tender, sore and red if they become infected. Foul-smelling pus coming out of the cyst is another sign of infection.
Can a cyst suddenly get bigger?
Cysts can remain stable or they may steadily grow. Sometimes they will become inflamed or suddenly break open (rupture).
