[|Human|] My four year old son was c/o his right middle finger itching while he was trying to go to sleep. I am leaning toward a tingling feeling, but I think he lacks the ability to communication it. No significant health history, although I am curious about anemia, due to his poor eating.
[|AI|]  DearWelcome to ChatDoctorWe understand your concerns went through your details. Neurodermatitis could be the possible cause. Neurodermatitis develops when nerve endings in the skin become irritated, triggering a severe itch-scratch-itch cycle. Common causes of nerve irritation include an insect bite and emotional stress. I suggest you to get an examination done from a dermatologist. It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. If you require more of my help in this aspect, please use this URL. http://goo.gl/aYW2pR.
