My scalp gets real itchy as does other parts of my body such as the lower back and generally all over but most intensely on the head/scalp area and back where I have been taking a higher strength antihistamine to help control for over a year now. If I miss taking the antihistamine the scalp mostly and lower back starts to get itchy and I then realize that I have forgotten to take the antihistamine. As far as scratching the itchy area, specifically the lower back, my fingernails will leave a line which looks inflamed from the scratching obviously which is typical I know if you scratch your skin but it appears to inflame more easily/quickly in my opinion. The redness and inflammation does go away with time as I don t scratch and the area is no longer itchy. A clinic doctor thinks I have sebhoric dermatitis but I know that this is not what I have. Can you please provide me with your thoughts, diagnosis and any recommendations. Thanks, Mike
