Itching (itch) facts

The medical term for itching is pruritus.
Infections, bites and stings, infestations, chronic diseases, sun exposure, and dry skin are among the numerous causes of itching.
Anti-itch creams and lotions containing camphor, menthol, phenol, pramoxine (Caladryl, Tronolane), diphenhydramine (Benadryl), or benzocaine can bring relief.
Some cases of itching will respond to corticosteroid medications.

If itching persists with time or worsens, or is associated with skin lesions, consulting a health-care practitioner is advisable.
