Numbness in left forehead. In neurology.

Hi, my sister was attacked by Dengue last month, though her platelets did not went down much, she wasn't hospitalized. She recovered in a weeks time, however later after few days she started getting Numbness in her left forehead, most of the times she gets headache, she says she could feel the pain inside the skull. 3 doctors has advised as this would have come due to stress in studies or due to any other stress by thinking something and have prescribed migraine tablets, but we are not satisfied with the solution., so looking out for the best neuro specialist like Dr.Pranesh who used to practice in Coimbatore., could someone help me in getting his contact details. He is little aged and have won more awards for his achievements for his services in neurology.
