my son scratches his head seriously when sleep since four months ago, I catch that two times at night-time. and quite often in day time like a habit, but in day time he is not scratches that hard. There are several blood shed on his head. I spot check his head few time in different weeks, one spot is wet blood fluid. I saw family doctor three times, but he has nothing to do. just told me if he stop scrratch his head, it will be okay. Is there any solution recommend?
What is your son age?  Is there any lesson over head, like Dan Chat Doctor.  Trim nails of your son so that there will be not bleeding from scalp by scratches.
