ROME (Reuters) – Excessive text messaging may be bad for you, or at least for your fingers.

That’s what some Italian doctors think. They are telling people, particularly the young, that furious typing on mobile phones could lead to acute tendonitis.

Italian newspapers La Repubblica and Il Messaggero dedicated about half a page each to the problem Monday. A 13-year-old girl in the northern Italian city of Savona needed treatment from an orthopedic specialist after typing at least 100 short message services (SMSs) a day.

She was prescribed anti-inflammatory medicine and ordered to rest her hands.

According to a recent study conducted for children’s rights group Telefono Azzurro, some 37 percent of Italian children are “cell phone addicts.” Irritability and mood swings were other symptoms linked to very frequent cell phone use among the young.

The message is clear: MayB U shd stop B4 its 2 L8.
