yeah, you are correct , but how does itching increase blood flow ? ? ?
Also, itching doesn't occur only due to wounds, in othercase it probably increases the blood flow to get u'r immunecells in that region and check any infection, so, this is the porpose of itching , but it would still arise due to nerve irritation, i think.
