Osteoid osteomas tend to be painful. They cause a dull, achy pain that can be moderate to severe. The pain is often worse at night. Osteoid osteomas occur more often in men than in women.

Can osteomas be painless?

Painless osteoid osteoma is a rare benign bone tumor [1]. Due to presence of a painless lytic lesion (nidus) with cortical sclerosis and thickening, it may be mistaken as chronic osteomyelitis or as Ewing sarcoma.

Are osteomas normal?

Osteomas are benign head tumors made of bone. They're usually found in the head or skull, but they can also be found in the neck. While osteomas are not cancerous, they can sometimes cause headaches, sinus infections, hearing issues or vision problems – however, many benign osteomas don't require treatment at all.
