Sebaceous cysts are usually painless, slow-growing, small bumps or lumps that move freely under the skin. Signs or symptoms that may indicate infection of sebaceous cysts include:
Increased temperature of the skin over the bumps or lumps
- Greyish white, cheesy, foul-smelling material draining from the bump or lump
Small cysts are typically not painful. Large cysts can range from uncomfortable to considerably painful. Large cysts on the face and neck may cause pressure and pain.
