If a person suspects that a medication is causing itching skin, they should speak to a doctor before coming off the drug.

At other times, they may recommend taking diphenhydramine (Benadryl) or hydroxyzine to reduce itching symptoms.


Nerve Disorders

Nerves relay messages from the skin to the brain. Problems with the nerves can cause itchiness or pain on the skin without causing any actual damage to it. Several nerve related conditions can cause itching or other sensations on the skin without causing a rash. These conditions include: stroke, diabetes, postherpetic neuralgia, a complication of shingles. According to the American Academy of Dermatology, diabetes can cause a range of skin issues. For example, itching can result from diabetic neuropathy, which is a complication of diabetes that causes nerve damage. Injuries that affect the nerves or cause nerve damage can also make the skin feel itchy. The area that feels itchy will depend on the location of the injury. Treatments for nerve related itching depend on the underlying cause. If a person suspects that they have a nerve disorder, they can talk to a doctor to learn about what might be causing specific symptoms.
