Painful Lump at Base of Skull: Causes & When to See a Doctor

While sinus infections can cause pain and pressure in the face and head, they typically do not cause lumps or bumps. If you have a painful lump at the base of your skull, it is important to see a doctor to determine the cause. It is possible that the lump could be caused by a sinus infection, but it is also possible that it could be a sign of a more serious condition, such as a tumor or an abscess.
