I don't think you should see a doctor now. First of all, I suggest you go to Dongsi Store of Yong 'antang to find a sitting doctor, Dr. Li Hongguang, who is a Chinese medicine practitioner. I recommended him because I had follicular keratosis before, but I didn't know about it at that time, so I went to see him by accident and was later cured. So you can go there and see if he knows what's wrong with you. Secondly, the biggest fear of getting skin diseases is cleanliness. I suggest you use Yang Ya's soothing spring water and cleansing soap, because it won't irritate your skin and can treat atopic dermatitis.
These are my two suggestions. I especially understand the pain of dermatitis. There have been several places. If you have any questions, you can email me, lee _ 0115@sohu.com.
