Also known as … Brachioradial Itch
Brachioradial Pruritus is a skin condition where the affected person is troubled by abnormal skin sensations on the outer forearms, upper arms and occasionally on the top of the shoulder. The affected person may describe the sensations as itching, burning, prickling or stinging.
Any changes seen in the skin usually result from chronic rubbing and scratching at the affected area. The skin may become thickened and pigmented. There may be breaks in the skin and nodules due to scratching. The affected areas frequently show changes resulting from chronic sun damage.
The condition is due to inflammation in nerve fibres within the affected area of skin. The inflammation results most commonly from damage to the sensory nerves in the skin caused by chronic sun exposure. Occasionally the nerves are compressed and damaged by changes in the cervical spine as a result of arthritis or age related changes.
The symptoms are often worse after sun exposure and the affected person may report fewer problems or no symptoms in the winter or autumn.
Brachioradial pruritus is diagnosed by taking a medical history and examining the skin. If the history suggests that spinal abnormities may be the cause, medical imaging such as CT scan and MRI may be needed.
The majority of cases in Australia are related to sun exposure. Some cases resolve within a few weeks to months with topical measures and sun protection. Some individuals have waxing and waning symptoms with episodic flare-ups of the abnormal sensations followed by periods when they have no problems.
