<s>[INST] About a month ago a red, dry patch appeared on my shoulder . I originally thought it was ringworm , but the anti fungal medication only made it worse. After applying the medicine, the patch grew from the side of a dime to the size of a quarter. It does not itch and is not painful. It is simply and red, scaly patch. What do you think it could be? [/INST] Hi, Thanks for writing in. The condition can be xerotic eczema,discoid eczema, ringworm etc. As it has worsen after antifungal application it is likely that it is eczema. You can apply a good moisturizer with shea butter twice daily along with mild steroid like hydrocortisone cream.Continue this for 2-3 weeks for visible effects. Hope this helps.
