<s>[INST] I get extremely itchy feet (the tops of my feet and ankles).  It happens sporadically and I've tried to eliminate foods/other allergens but there seems to be no rhyme or reason.  I can go months without an attack then in the last few weeks I've had to take allergy pills several times - if it was the new detergent why wouldn't I itch all the time?  It happens more in the evening and more in winter - it's not dry skin, or exzema/psoriasis (which I have had on my arms).  any ideas [/INST] Welcome to Healthcare-MagicGreetings of the dayIt's sometimes very difficult to base the diagnosis of skin condition based only on description, it becomes equally important to examine the site for right diagnosis.I would suggest you either consult a dermatologist or send  the clinical photograph at Healthcare-Magic so that expert opinion is given for tiger lesion on questionTake careRegardsDr T ShobhaMBBS MD </s>
