A skin cyst is a kind of skin disease that is very common and harmless. This fluid-filled lump underneath the skin may get well even without treatment. Cysts are sometimes misunderstood as boils or skin abscesses. Boils and abscesses that develop in the skin are very painful because of collections of pus that result in infection.
Even though they are not cancerous, a cyst can be irritating somehow. A cyst is not that harmful and is a non-cancerous type of skin illness.
Sometimes a skin cyst grows slowly but it doesn’t cause too much pain. However they become infected; that’s why it may turn red and swollen.
Proper care can diminish discomfort and pain.
