[|AI|]  Recent increase in the size of the spot on the scalp which you mentioned is something to be worried about. Is the any pain, itching or redness over the spot, and how are the borders of the spot is it - regular and well-defined or irregular and ill defined? How was it progressing - gradual or sudden? sometimes a spot like melanotic spot may have serious consequences and your suffering from chronic migrant that is dull aching pain. So it is always advisable to consult a neurologist and a dermatologist for physical examination. You may require a CT scan brain and a skin biopsy from that spot over the scalp.
