[|Human|] I have a lump on right side of my head about an inch above my ear. its about the size of a nickle and soft doesnt hurt. was there out of nowhere for about three weeks. now im getting headaches and feeling pressure at times where the lump was. it went away and now is hard and the size of a pea. What is this?
[|AI|]  Hi.it is best if you consult with a doctor for physical examination and clinical evaluation. Diagnostics, such as imaging (x-ray, ct-scan or MRI) and biopsy, may be suggested for further evaluation of the mass, which could be any of the benign lesions (cystic formation, lipoma or hematoma). Other tumor types (such as malignancy) must also be ruled-out. Management (medical and/or surgical) will be directed accordingly. Hope this helps. Good day!!~ Chat Doctor.
