A hard bag on the forehead is painful to press, it may be a pink tumor, or it may be a frontal bone growth or deformity. It is recommended to go to the hospital for examination, and if it is a powder tumor or lipoma, it can be removed surgically. If it is a frontal bone enlargement, you need to consult a professional orthopedic surgeon to see if surgery is needed. Do not press or squeeze the hard pack for a long time to avoid inflammation and infection. If there is already an infection, you need to apply antibiotic cream locally or take oral antibiotics in combination.
