<s>[INST] 4-6 weeks ago i thought i had what was an allergic reaction to shower gel and lotion on my legs below the knee.  Now i still have some dry skin, but i also have a circle almost the size of a nickel that is sorta scabby around the outside and just very tough smooth skin in the center.  it started small but got bigger.  i quit using the shower gel and stuff and got a mild moisturizer but its not going away [/INST] Hello. Thank you for writing to us at healthcaremagicI suggest a possibility of discoid dermatitis.Dry discoid dermatitis usually presents with disc shaped dry and scaly patches. They are usually itchy.Underlying dry skin is a predisposing factor.I suggest that you continue with the moisturizer over affected area, twice daily.Specifically for the patches I suggest you to use a topical potent steroid+ antibiotic combination cream, twice daily, over and above the moisturizer.An OTC oral antihistamine e.g cetrizine 10 mg once daily will provide you symptomatic relief from itching.Avoid soaps. Soaps are too drying. Use a gentle cleanser e.g cetaphil cleansing lotion rather than soaps.Regards </s>
