Hello Doc.. i am not sure if this is a medical issue but i m bothered with my 2 daughters.. my 3rd child, she is 12 years old and likes to rub rough surface in her body. The latest area the she keeps on rubbing unconsciously and repeatedly now is her dry lips..i already applied many times lip balm to keep her lips moisten but she will find another part on her body that is rough (such as dry wound).. it is her mannerism that even in school she is doing it.. then my youngest daughter, 11 years old..had this strange mannerism also.. except that she likes scratching her scalp then sniffing her fingers after scratching her scalp..or sometimes...she sniff repeatedly and very loudly..i already explained her to stop this as she can irritate her sinus but to no avail.. i am bothered with their behaviors...is there something wrong with them ?.. thanks doc and more power..God bless you..
Hello, As per your history, I think your both daughters are suffered from chronic itching. Before diagnosing as it is there behavioral problem, we have to find out other causes of chronic itching. Common causes of itching are:1) Allergic reactions2) Chat Doctor.  So, I will suggest you to review here with detailed history or consult with the dermatologist. Hope I have answered your query. Let me know if I can assist you further.
