Scalp Itching Caused By Dermographism
I have all the classic symptoms of Dermographism on my back and arms and some places on my legs. But I also have severe itching on my scalp and I can feel small welts which come and go with the severity of the itching. If I can refrain from scratching my scalp the welts do not come and I try to not scratch but rub the itching area as little as possible. Sometimes I wake in the night and I am really scratching my scalp with a vengence. It soon stops and I am able to go back to sleep. I have no itching at all on my face, thank goodness. Thank you for any help you can provide in dealing with this problem.
It is not that unusual that a specific area is affected. Your best option is to use an antihistamine, perhaps just before bed, to try and relieve or prevent the onset of night time scalp itching. Speak with your doctor or pharmacist to determine the right antihistamine product to use.
