<s>[INST] I have this white, flaky scab like thing on my knee.I don't recall getting any cuts there and I don't know what cause it.I usually don't put on lotion and I thought it was because my skin is dry..But it's just that part.What is it and how do I get rid of it? [/INST] Hello,Welcome to healthcare magic,From your description I feel it could be psoriasis as it is a very common site. Kindly consult a dermatologist to confirm the diagnosis. Please apply a moisturizing cream every day twice daily over the lesion.Hope this helped,Take care. </s>
