Can steroid injections treat lichen simplex chronicus?

Lichen simplex chronicus is skin that becomes thick, leathery, and itchy after repeated rubbing or scratching. The itch encourages more scratching, creating a self-reinforcing cycle. A clinician may place steroid into a localised, thick patch when surface treatment has not been enough or when the area is difficult to treat with other methods.

The injection addresses inflammation within the selected patch, not the source of friction, allergy, dryness, stress-related scratching, or another condition that started the cycle. A clinician may check the site carefully because fungal infection, eczema, psoriasis, or another lesion can sometimes look similar.

Arrange an examination if the itch persists, the patch spreads, or the skin becomes painful or cracked. Keep nails short, use the recommended moisturiser, and reduce known friction while following the treatment plan. Tell the clinician about night-time scratching, sleep disruption, allergies, and previous creams. Do not inject the area yourself, and do not keep scratching through worsening pain.

Seek prompt care if the patch develops pus, warmth, rapidly increasing redness, open sores, or severe pain. Urgent review is needed for fever, spreading redness, facial or eye involvement, or swelling that affects breathing. A patch that changes quickly or fails to improve should be reassessed rather than repeatedly treated without a diagnosis.

Ask what is driving the itch-scratch cycle, whether the patch is suitable for injection, how to protect the skin afterward, and which daily measures can prevent rubbing from restarting the thickening.
