[/INST] Hi, It seems that you may be having allergic dermatitis on both feet. There may be Chat Doctor.  There may be secondary bacterial infection, that is why toes may be swollen and reddish. There may be some cause like.house dust, dander,grass, soap,socks, clothes,soap, shoes,leather, water...etc. You consult dermatologist for firm diagnosis and treatment. To relieve itching, antihistamines like levocetirizine or desloratidine may be taken. Short course of antibiotics may be taken. If needed, steroids in tampering dose may be taken. Application of mild steroid like mometasone might improve the lesions. Avoid soap bath. You may use detail for cleansing the feet. You might improve after few weeks' treatment. I hope you got my answer. Thanks. </s>
