Sir last 3 days in my center left head i feel little bit numbness, but no pain, no headache .... if i will touch means i will can feel but not like a other place of head, plzz?

It sounds to me: like you are trying to describe a loss, not total, or change of sensation when you touch your head/scalp. This would typically result if there was injury (cut, laceration) that impacted the nerve supplying this area. Perhaps that area of your scalp is especially sensitive to a hair product/shampoo, etc. Change to a non-irritating shampoo, watch and wait. If symptoms intensify or expand, see Doc!
