It seems that you are having scalp prurigo
It is related with psychological upsets.
So, be calm and cool.
Take antihistaminicslike levocetirizine
Take anxiolytic like fluoxetin.
But , after consulting dermatologist
, take the treatment.
You cleanse the scalp with antiseptics like savlon.
Avoid stress and worries.
The veins like lesions might be the thickened skin, which may be improved by proper treatment..ok
I hope you got my answer.
