[|Human|] I have had a two dark brown patchy spots that look like skin rashes for about a year now on my left ankle. I have had creames to rub on from my doctor but it never healed, it only helped with the itching a bit, but it itches from time to time. I want it to be healed what else can I do? What might it be?
[|AI|]  Hello. Thanks for writing to us at Chat Doctor I will keep a possibility of Lichen simplex chronic us (LSC). LSC usually presents as hyperpigmented, Chat Doctor. The skin gets thickened because of constant scratching, these thickened patches in turn generate the desire to itch and therefore this forms a self-perpetuating cycle:itch-scratch-itch cycle. Treatment involves Oral antihistamine e.g. cetirizine 10 mg once or twice daily, which suppresses the desire to scratch. Topical application of potent Or super potent steroid e.g. clobetasol propionate ointment Or Clobetasol propionate ointment, twice daily is very useful in LSC. Steroids may be required top continue for weeks Or months to achieve desired results. Intralesional steroids are better options as compared to topical steroids and are usually administered into the lesional skin once every 2-3 weeks. I would suggest that you seek an appointment with a specialist dermatologist in your region for a confirmatory diagnosis as well as appropriate prescription. Regards
