Finding a sudden bump beneath your skin can instantly trigger panic and make you worry about serious illnesses. However, most of these growths are simply cysts, which are harmless, fluid-filled sacs that develop painlessly over time.
These lumps typically form when oil glands get blocked or minor skin injuries trap tissue beneath the surface. Because they grow slowly and quietly, you might only notice one when brushing against your skin.
Never make the mistake of squeezing or attempting to pop a cyst like a regular pimple. Squeezing can push trapped bacteria deeper into your tissue, causing severe infections, painful swelling, and permanent scarring.
While the vast majority of cysts are completely non-cancerous, you should still consult a doctor if one becomes hot, red, or painfully inflamed. Medical experts can easily and safely remove or drain the sac in just a few minutes without leaving noticeable marks.
